Introduction
According to the popular online magazine Slate, outrage is the dominant mode of engagement with social media.

But what about controversy? Just a glance at the lists of “trending topics” on popular platforms like Twitter, Instagram, or Facebook reveals a host of scandals, debates, disputes, and polarizing campaigns. However, if something akin to controversy is prominent in social media, it is nevertheless particular types of controversies. Many disputes and debates unfolding in these settings are concerned with events and problems pertaining to some aspect of social media and/or digital culture itself, as in the case of the #gamergate scandal foregrounding misogynism in digital media industries as well as in online debate spaces, or mobilization around Facebook’s dubious or illegal practice of scanning private messages (#scan) on Twitter.

This reflexive quality of controversies—about things digital, unfolding on digital platforms—has by no means gone unnoticed in social, cultural, and anthropological studies of digital media technologies and culture (Bruns & Burgess, 2011; Crawford, 2013; Kelty, 2005). However, this feature of digital and social media controversies also has important
Controversies unfolding in social media settings bring into relief a feature of controversies as a research object that has long interested scholars in media, social, and cultural studies (Latour, 2005; Lievrouw, 2009): they present researchers with
In our view, this ambivalence around the object of research arises especially forcefully when implementing controversy analysis as a social media method. Indeed, this methodological issue seems of
To begin with, we will provide some brief background and key principles of controversy analysis in STS and some related work in sociology and media studies. We then discuss recent attempts to implement controversy analysis as a digital method, with a special focus on social media. We argue that recent efforts in this area bring into relief the aforementioned tension surrounding the framing of digitally mediated controversy as both an empirical object and method: while some controversy analysts approach social media primarily as a
We will argue that this ambivalence, uncertainty, or variability in the framing of controversy analysis as a social media method is problematic, and needs to be explicated, but that the resulting tensions may also be productive and, indeed, may inform further development of the approach. To clarify why we think this is so, we will discuss different ways in which the problematic may be addressed
Controversy Analysis as an STS Method and the Role of Media and Media Technology
Controversy analysis is a methodology developed in the inter-disciplinary field of STS for the study of public disputes about science and technology, and the interaction between science, innovation, and society more broadly. 4 This work goes back many decades; one important historical marker is the work of the Edinburgh School in the sociology of science. David Bloor (1982), for example, analyzed the historical controversy between Robert Boyle and Thomas Hobbes about the corpuscular theory of matter, showing how this 17th-century controversy was not only about epistemic issues but political ones as well. His sociological study of controversy showed how competing knowledge claims contained within them assumptions about how to imagine social order. Furthermore, Bloor and his colleagues posited that in the midst of a scientific controversy, neither side has “truth” on its side, and the analyst should therefore set aside true and false and treat all positions as scientifically viable. Doing so reveals that all sides have to make arguments that include a socio-political dimension because they can’t rely on “but it’s true because we’ve proven it to be true.” One of the central tenets of controversy analysis as developed by Bloor and his colleagues, then, was the “symmetry principle”: the idea that both “true” knowledge and discredited “false” knowledge (or epistemic content) have a socio-political dimension and that, accordingly, we must always be studying both at the same time: the knowledge content and the political position taking, the epistemic configuration, and the power constellation.
Controversy analysis was also crucial in the subsequent development of Actor–Network Theory (ANT), which extended the symmetry principle to develop a new approach to controversies. According to actor–network theorists like Michel Callon (1986) and Bruno Latour (1987), the Edinburgh approach was “overly theoretical”: they argued that when analyzing controversies, we should not decide on conceptual grounds how science and society, and knowledge and politics are related (or not), we should treat controversies as “empirical occasions”—events that render legible and “researchable” relations between a whole variety of heterogeneous actors from science, society, politics, industry, and so on. Furthermore, in developing their approach, in empirical studies of historical and contemporary controversies around innovations like the diesel engine and the electric car, Latour and Callon proposed that not just truth and falsity should be treated symmetrically, so should human and non-human actors (nature, microbes, scientific instruments, etc.). In their account, controversy and innovation unfold in social and epistemic, political, and technical dimensions all at once, and indeed, the merit of controversies as research objects is that they render visible “heterogeneous entanglements” between different types of entities.
ANT then critiqued the overreliance of the earlier, sociological (post-Marxist) approach to controversy analysis on rigid conceptual categories, such as the imputation of “interests” to actors. In the ANT account, social studies of controversies should not seek to impose their own theoretical definition of what is at stake in controversy. Rather, they should “follow the actors” (both human and non-human) in their (competing) attempts to define the controversy (Latour, 1987), or as we would say today, we should map the issues (Marres & Rogers, 2008; Rogers & Marres, 2000). Controversy analysis enables an “empiricist” style of inquiry: in moments of controversy, when identities are at stake and assumptions become unsettled, we must suspend our (conceptual) assumptions as to what are the constituent elements of the empirical phenomenon under study. It also means that the social researcher should not decide on conceptual grounds
Indeed, in later studies, controversy analysts were forced to confront the role of public media in the mediation of techno-scientific issues (Gieryn, 1999; Hilgartner, 1990; Lewenstein, 1995; Nelkin, 1987). Studies of public disputes about, for example, nuclear power (Nelkin, 1971), genetically modified (GM) foods (Jasanoff, 2005), and road construction (Barry, 2001) paid special attention to the ways in which media, particularly news media, participate in the articulation of science and innovation, often framing them as topics of public debate and controversy. Yet, the media have historically been approached with some reticence in STS: much of the work was initially primarily interested in tracking the trajectory of scientific disputes “within science,” and from this perspective, the media do not necessarily have any significant impact on the trajectory of controversy (Pinch, 1994). Others suggested that “the media” selectively direct attention and resources in techno-scientific controversies (Callon, Lascoumes, & Barthe, 2001), but without necessarily affecting the substantive knowledge content or regulatory regimes. And while the situated locations in which controversy unfold have been investigated in great detail by controversy analysts, including the laboratory (Latour, 1987), the scientific literature (Leydesdroff, 1989), and policy think thanks (Stilgoe, 2012), rarely have public media been investigated with the same ethnographic rigor as a site of scientific controversy (Barry, 2001; Gregory & Miller, 1998).
It is therefore not surprising that when STS researchers turned to the Internet to analyze controversies in the late 1990s, they were primarily using digital settings in a rather instrumental fashion, to analyze public controversies about science and technology that occurred in but extended beyond them, such as climate change and GM food debates (Beck & Kropp, 2011; Rogers & Marres, 2000). At the same time, however, it was clear from the start that the significance of the Web as a site of controversy derived from the proliferation of new digital, networked
These developments signal possible transformations in the ways in which we conduct public controversies in our societies and cultures, transformations that we should research
The formative ambiguity deriving from mediation presents a long-standing concern in media and communication studies (Lievrouw, 2009; see also Bolter & Grusin, 2000), 7 but coming from STS, it can be taken as an invitation to formulate another “symmetry principle,” this time specifically for the study of controversies with online media technologies. This version of the symmetry principle pertains not to “knowledge” and “politics,” but to “content” and “media.” It states that when analyzing controversies unfolding in digital media settings, we should not explain “failed controversies” in terms of the influence of media-technological dynamics (e.g. the capture of the controversy by dubious search engine ranking logics), while explaining the “robust controversies” that we detect online in terms of topical dynamics (e.g. by stakeholders in agriculture policy organizing into an online issue community). Instead, we should assume that failed and successful controversies are both likely to be marked by media-technological and issue dynamics.
A concern with the relations between media-technological and content dynamics in controversy is certainly not new nor is it specific to digital settings. Among others, it has previously been explored in debates about the media-specificity of public debate and issue formation (Corner, Richardson, & Fenton, 1990; Meyrowitz, 1997; Morley, 2006). But the methodological contribution that STS approaches to controversy analysis can make to its clarification remains to an extent unexplored (though see Hilgartner, 2000), and it seems to us that there is something about the analysis of controversy
Controversy Analysis as a Social Media Method
Current attempts to harness social media for controversy analysis build on earlier Web-based methods of online controversy analysis and visualization. From the late 1990s onwards, researchers in fields as diverse as sociology, media studies, computing, and STS have developed digital techniques to analyze controversies unfolding on websites, blogs, and the result pages of search engines. Much of this work drew on established methods of scientometrics, translating citation analysis into methods for the analysis and visualization of hyperlink networks (Rogers & Marres, 2000; Scharnhorst & Wouters, 2006), and used methods of textual analysis to interrogate the substantive dynamics of controversies online, as in blog analysis of climate and 911 controversies (Foot & Schneider, 2004; Prabowo, Thelwall, Hellsten, & Scharnhorst, 2008). The rise to prominence of social media platforms over the last 10 years or so has both provided a new impulse to implement controversy analysis by digital means but also raised new challenges.
“Social media” hold significant promise for controversy analysis for two main reasons: first, they signal a further mainstreaming and/or wider uptake of digital media technologies in and across social, professional, and public life (Gerlitz & Lury, 2014), thereby extending their empirical relevance as a setting for societal controversies. Second, they make available
Especially relevant for controversy analysis is that these digital action formats can be deployed to analyze “topical activity” or social and political content dynamics online. Thelwall, Sud, and Vis (2012) have analyzed “reply chains” on YouTube to detect debating activity, identifying especially active or “hot” or controversial topics (religion, as opposed to music) and the variation in topical engagement over time and between topics. In the project “Political Hashtags,” Weber et al. (2013) sought to detect the political “leaning” of hashtags on Twitter, by analyzing which actors are associated with these hashtags. As already noted, Bruns and Burgess (2011) and Burgess and Sauter (2015) analyzed the formation of “issue publics” around specific hashtags, including those related to agricultural advocacy in Australia, with the latter drawing explicitly on STS work on controversy analysis. Papacharissi and de Fatima Oliveira (2012) have used computational discourse analysis to study social and political engagement with a specific hashtag (#egypt) developing an account that foregrounds the role of drama and affect in the formation of publics. This work combines network and content analysis to unearth “heteregenous communities” forming around contested topics in social media. Controversy researchers have also turned to Wikipedia to analyze controversy dynamics, as in the work by Borra et al. (2014) and Yasseri, Sumi, and Rung (2012), which rely on platform-specific formats (the edit, the fork) to detect the relative controversiality of Wikipedia articles on substantive topics including climate change, Sigmund Freud, 911, and so on. Finally, a younger generation of scholars is testing the capacities of social media platforms like Facebook for the qualitative study of controversies across settings, combining network analysis with discourse analysis (Birkbak, 2013; Plantin, 2011).
This brief overview makes clear that the development of controversy analysis as a social media method is very much an inter-disciplinary endeavor, which draws on a variety of methodological traditions. Perhaps it is partly for this reason that many of these projects evince the ambiguity we invoked in the introduction: while their overriding ambition seems to deploy social media platforms in an instrumental fashion, namely, as empirical settings-tools for the analysis of substantive dynamics of controversies online, several of these projects are primarily concerned with elucidating dynamics specific to the digital media platforms at hand, answering questions such as “Which topics are especially conversation-inducing
This ambiguity of the “empirical object” of controversy analysis as a social media method does certainly not go unrecognized, for example, when the empirical object of social media research is defined as “communication flows in society” (Bruns & Stieglitz, 2012) or “social media networks” (Smith et al. 2014).

Previous discussions of Web-based methods also highlighted the Janus faced nature of online research, with Foot and Schneider (2004) noting that some forms of analysis were concerned with “web-based phenomenon,” while others investigate the connections with “factors exogenous to the Web.” However, it seems that several features of online platforms combine to make this issue particularly pronounced in social media research. One reason is the often-noted reliance of much social media data analysis on application programming interfaces (APIs), which means that platform architecture can exert significant influence on research design (boyd & Crawford, 2011; Marres & Weltevrede, 2013). (As Thelwall et al. [2012] note in their study of YouTube comments: “A more general limitation is that the results are based upon convenience data
The issue of “platform bias” in social media research has received a fair amount of attention in recent years (Driscoll & Walker, 2014; Tufekci, 2014). However, it strikes us that much of the debate about platform bias assumes a fairly stable methodological framework—broadly in line with “scientific empiricism.” What we are interested in here is how the problem of platform bias forces
In proposing this, we align ourselves with the argument by Rogers (2013) that the role of social media architectures in the organization of controversy in these settings
To be sure, this problem is sometimes a specific one that can be alleviated through specific measures (e.g. in conducting hyperlink analysis of controversy networks on the Web, it is a good idea to block links to “purely technical” addressees [e.g. Firefox]). But in other cases, the problem is a more open-ended one: it has to do with the ways in which the chosen setting (social media platforms) and methods (reliant on platform devices) conspire to render particular phenomena available for analysis, in a way that renders impossible any neat distinction between object and method (Cicourel, 1964). In the practice of social media research, it is often difficult to make clear-cut distinctions about what belongs to the “empirical object” and what belongs to the socio-technical apparatus of research. Such lack of clarity arises, for example, when controversy analysis encounters a hashtag like #FF, which stands for #FollowFriday, an invitation to select new users to follow every Friday. The question is as follows: does the presence of such a tag in a Twitter data set indicate noise, a tell-tale symptom of bad research design, and thus requiring exclusion, or does it present a positive contribution to the controversy under study?
The mixture of methodological and empirical issues that is brought into relief by the uptake of controversy analysis in social media research then raises some tricky questions about the framing of its empirical object. These questions can perhaps never be neatly resolved; the question is how seriously to take these issues, and when to do so. Some social media researchers might prefer to adopt a straightforward empirical framework in conducting controversy analysis, and look for ways to contain the methodological problem of “platform bias.” From this perspective, engaging with more “fundamental” questions—“what are we analysing when researching controversies with social media?”—threatens to distract from the challenging technical and analytic work at hand. But we would like to propose a different way into (and out of) the problem: the methodological ambiguity of controversy analysis does not just present a general or formal problem, it equally confronts us
Three Ways of Analyzing Controversies with Social Media: Precautionary, Affirmative, Empiricist
No doubt the most familiar way of dealing with the influence of social media platforms on the enactment of controversy online is to adopt a “precautionary approach” toward the problem of “platform bias.” Assuming a largely negative understanding of the contribution of digital platforms to controversy, the researchers aim to clean the data and remove platform artifacts (for a discussion, see Rogers, 2013). A clear example can be found in the treatment of bots in social media research. For example, when setting out to map controversies around “privacy” on Twitter in the summer of 2013, we were struck by the predominance of generic content associated with the hashtag #privacy on Twitter. Among the hashtags used most often in combination with #privacy, we found astrological signs (#pisces, #aquarius, etc.) and generic media terms like “#blog” and “#email,” something that was probably due to marketing bots hijacking trending topics on Twitter. 12 Our instinctive response was to “remove the bots,” to delete from our data set all tweets using these generic hashtags. The objective, when operating in this mode, is to secure the empirical viability of social media analysis: to make sure that we are mapping the issues and not allow our analysis to be hijacked, in turn, by “platform artefacts,” that is, the bots attracted to popular topics.
One of the limitations of a precautionary approach, however, is that it assumes a largely negative understanding of the participation of digital platforms and its attendant devices in controversy online. The “performative” approach to the role of digital devices in controversy, discussed above, is designed to replace this with a more positive appreciation. Examples of a more affirmative approach to “the influence of setting” can be found in studies that compare country-specific search engines for their “representation” of a given topic (Koed Madsen, 2012; Rogers, 2013). Precisely because digital platforms rely on medium-specific metrics to identify sources relevant to a topic, this work proposes, they can reveal relevant inflections in the mediation of controversial topics. In other words, precisely because engines count links, consider timestamps, and so on, they are able to reveal the political charges of “content” that controversy analysts are interested in. A comparison of query returns for “elderly care” in country-specific Googles by Niederer et al. revealed significant differences among countries, with charity organizations featuring prominently in some, while in other cases, public sector institutions featured more prominently. 13
However, one could say that the affirmative approach works only as long as the above problem of methodological ambiguity can be bracketed. Here, the question “are we studying media-technological effects OR substantive issue dynamics?” is the wrong question. However, this becomes difficult or unhelpful to sustain when this
When analyzing controversies with social media, we then make it our empirical task to investigate which effects belong to media technologies, which to the issues, and which to both. Rather than assuming a stable object of analysis, the qualification of the empirical object here becomes the objective of research. This, in turn, requires that our research design is as
Testing the Three Approaches: Mapping Privacy after Snowden with Twitter
The above three approaches each belong to different methodological—or philosophical—universes, which we could arguably label as (a) scientific empiricist, (b) performative, and (c) radically empiricist. However, from a practice-based perspective, the three tactics may well be complementary, and the question then becomes under which conditions they are most useful, and what their specific merits are. Here, we take up this question by discussing some examples from our own social media research practice, focusing on a pilot project in which we turned to Twitter to detect controversies and issue formation in relation to privacy in June 2013, the period in which Edward Snowden publicly leaked National Security Agency (NSA) files.
We chose this focus because both the issue (privacy) and the event (NSA leak) operate in several dimensions: privacy is a long-standing concern of activism and advocacy in digital culture, with significant ethical, technical, and economic dimensions. The NSA leak, furthermore, not only received significant attention from news media—the Guardian newspaper played a key role in publicizing the leaked documents—it also addressed and connected with digital activist networks, gaining much exposure across the Web and online platforms, including Twitter. As such, this case is highly ambiguous—in the positive sense—making the composition of the issue and the relations between different mediators (social media, news media, advocacy and activist networks, and so on) complex and multi-faceted. 15
The above diagrams (Figure 1) provide an initial indication of how the issue of privacy changed on Twitter in the wake of the Snowden leaks.
16
These figures depict hashtags that were prominently associated with the phrase “my privacy” on Twitter before and after the Snowden affair broke in June 2013. It suggests that the composition of the “privacy issue” changed significantly during this period. Perhaps, counter-intuitively, they suggest that communication around privacy on Twitter became

In our account below, we test the ability of our three empirical approaches to deal with this question. For this study, we derived our data from TCAT, the online tool for Twitter data capture and analysis developed by the Digital Methods Group at the University of Amsterdam (Borra & Rieder, 2014), which includes a number of tools developed as part of the Economic and Social Research Council (ESRC)-funded project Issue Mapping Online led by Marres (http://www.issuemapping.net) at Goldsmiths, University of London. Our data set is based on two queries—“privacy” and “surveillance”—and includes all tweets containing these words between 6 and 12 June, the period in which the NSA leak occurred. We initially included both terms as it seemed the NSA leak especially resonated across these two topics. 17
In Precautionary Mode
At the outset of any Twitter research, it seems intuitively sensible to adopt a precautionary approach, not least because of the “unclean” quality of any data gathered via Twitter’s API, as in the case of our “bot-infested” privacy data set discussed above. Cleansing our data of such generic content also serves a practical purpose: data reduction is often a practical necessity in online data analysis. At the start of our investigation, we turned to Gephi, the popular tool for network analysis and visualization, in order to visualize the whole data set and to delete from it any data that did not directly pertain to our controversy, the NSA leaks. We began by extracting from our data set a network of hashtags and users. In this bi-partite network (Figure 2), users (red nodes) are connected to the hashtags they use (blue nodes); the more times they use them, the stronger the connection (thicker lines). One of the advantages of this measure is that it mirrors a key commitment of controversy analysis as an STS method: to investigate connections between content and actors, between substantive knowledge claims and the social/political positions of users.

Hashtag-user bi-partite network, all data. Nodes sized by degree count (number of connections) and arranged using Force Atlas 2.
Presented with such a “hairball,” we could have taken several approaches to data cleaning. One simple option was to remove the top end of the graph—the nodes #privacy and #surveillance were part of the query, so their presence in the graph is not surprising or illuminating. 18 However, we didn’t want to upset the thematic coherence of the network at this early stage, and we made the simple if not unproblematic decision to remove the bottom end of the graph, filtering out users tweeting less than 5 times and excluding hashtags used less than 50 times.
However, no doubt the “easiest prey” for such acts of data cleaning are the aforementioned bots, and data visualization offers a useful way to find them. In examining our network, we noted several suspiciously thick edges between certain nodes (see Figure 3). These indicate a single user deploying a single hashtag over and over—which might represent an overzealous user, but more likely an automated bot.

Crucially, however, many of the top bots on the list are not so easy to dismiss
In Affirmative Mode
Rather than approaching platform-specific activity like that of bots as external to the dynamics of issue formation, we may also adopt the opposite approach, and consider how platform-specific dynamics may be an indicator of issue activity (Marres & Rogers, 2008; Rogers, 2013). In the wake of the NSA leak, a variety of more or less “media-specific” tactics were pursued on Twitter: circulating news through retweets, wry commentary including tags and mentions, links to online how-to-guides for anonymous browsing. This is to say that issue engagement on a platform like Twitter does not just involve “substantive position taking,” a primary focus on controversy analysis in STS, but relies on a wide variety of information formats, something that invites a broader focus on issue analysis rather than only controversy analysis (Marres, 2015; Rogers et al., 2015). 22 Here, the object of research is to analyze the articulation of “topics of concern” in different registers (humor, advocacy, knowledge) rather than to trace focused disagreement about specific knowledge claims.
One example of an affirmative approach in digital issue analysis is the practice of tracing the circulation of URLs in social media. Using a prototype tool called the “URL sequencer” currently being developed between the University of Amsterdam and Goldsmiths, we can visualize the trajectories of a URL being spread on Twitter. 23 The URL is a somewhat under-studied data object on Twitter (Bruns & Burgess, 2012; Lerman & Ghosh, 2010), despite the fact that it may provide important insights about cross-platform dynamics. Especially interesting are the modifications of a tweet containing the URL (retweet, @reply, comment, and so on), which may re-direct the reference to a slightly different potential audience (Murthy, 2013). We speculate that retweets of URLs here become technical tools for struggles over issue definition. Plotting URL trajectories in our Twitter data set then brings into view different social media tactics pursued by different actors in disseminating references and/or thematizing issues.
Analyzing the trajectories of top URLs in our data set, we identified three relatively distinct tactics of URL sharing. A first mode of link sharing that we dub “grassroots,” as information sharing here takes the form of a distributed process.
Take as an example the URL of the advocacy organization Privacy International (Figure 4), which was retweeted among users who generally took care to attribute the tweet to the user they copied it from, allowing a user network to potentially grow as these users attract followers. The graph above collects all tweets containing a particular URL (after tiny URLs and similar formats have been expanded) arranged in time order and separates them into colour-coded columns, each representing a sequence of mostly identical retweets (disregarding different attributions - @user and automatic truncations “…”. A second type of circulation we refer to as the “broadcast” mode, as it involves the use of semi-automated bots and services to disseminate information widely. In the case of the article by Security Affairs (Figure 5), two columns correspond to several identical messages sent by the publisher of the story through their Linked-In account (the green column), which then elicits retweets from other users. 24 A third and final mode of circulation we call “spin,” which involves the proliferating of unique tweets in which individual users overtly modulate the link by commenting on it as they forward it (Rieder, 2012). Thus, in the original Guardian exposé by Glen Greenwald (Figure 6) in which the NSA’s domestic surveillance program was first announced, one can see quickly accumulating unique phrasings rather than blocks of identical ones. There is evidence of Really Simple Syndication (RSS) 25 bots such as Tweet Deck sharing the article, but the URL’s trajectory shifts when the “hacktivist” collective Anonymous represented by @YourAnonNews (blue) takes up the URL and user @attackerman reacts to former Vice President Al Gore’s denouncement of the NSA program: “So this happened. MT @algore Is it just me, or is secret blanket surveillance obscenely outrageous? URL” (the beige strip in the visualization).

Focusing on a platform-specific feature, URL sharing, we thus get to view different tactics pursued to public-ize the NSA leak. Distinguishing modes of circulation is useful for controversy analysis, as it brings into view “issuefying” operations
In Empiricist Mode
To address this creeping concern, we adopted an experimental research design in which we sought to determine to what extent Twitter activity in relation to the NSA leak followed issue activity in the news media, or whether it also displayed issue dynamics that were to an extent irreducible to the “news cycle.” There are many assumptions and further questions packed into this question, concerning the supposed autonomy of social media platforms in relation to media organizations as well as the relations between news cycles and wider issue cycles (Coleman, 2011). We certainly cannot unpack these assumptions here: in analyzing privacy and surveillance issues with Twitter after the Snowden leaks, our aim is to evaluate whether we can map issues in a way that does not negate platform-specificity, but at the same time remains focused on tracing substantive issue formations. To this end, we use a Twitter tool designed to analyze content dynamics over time, the Associational Profiler. We plot which prominent hashtags are associated with “#privacy” and how this changes over time. 26 Figure 7 suggests that the top hashtags associated with privacy in the selected period are closely related to the staggered release of the Snowden files over the week. The hashtags closely follow the news media keywords and so we ask “what happens if we (temporarily) remove the news-centric hashtags?”

Hashtag profile of privacy in the “privacy” and “surveillance” Twitter data set, the Associational Profiler.
We then decide to strip away overtly “newsy” hashtags and their associated activity from our data set, in order to find out whether any issue formations remain. To determine the set of “newsy” hashtags, we use a timeline of the Snowden scandal usefully presented by the BBC, 27 which summarizes the sequence of events: from June 6, when the Guardian revealed government phone tapping by the company Verizon, to the revelation of the government program known as PRISM that collected online records with the complicity of Google and Facebook (but notably not Twitter) on June 7, then Obama’s statement on the June 8, and the revelation of Snowden’s name on June 9. We then (temporarily) blacklist all hashtags referring to the news events listed on the BBC timeline (nsa, prism, snowden, google, verizon, facebook).
Without the newsy hashtags (Figure 8), the profile for “privacy” becomes more issue-specific, insofar as it now primarily contains substantive issue terms (surveillance, security, data tap). Profiling these focus words in turn, we find that they contain terms one would not expect to find in the news media, including hashtags like “policestate,” “nwo” (for new world order), and “bigbrother.” As such, we hypothesize that Twitter does not just further spread news articles, but may indeed be participating in the substantive specification of the NSA leak as a matter of concern.

Conclusion
What are we mapping when mapping issues with social media? When we take up tools of online data analysis in order to map controversies with social media, we are confronted by this methodological issue, and we have proposed that STS approaches to controversy analysis may help us to address it. While methods of controversy analysis are used to analyze social media content across fields, STS methods are useful insofar as they explicitly recognize the “heterogeneous” constitution of the object of analysis. In turn, social media research provides important opportunities for further developing this methodology. In analyzing controversies, or mapping issues, with a platform like Twitter, we have the opportunity to elaborate a
While controversy analysts in STS have in the last decade or so stepped up efforts to account for the role of public media in controversies, social media research allows us to further operationalize the twin concern with both substantive and media-logical dynamics of controversy. This also means that in implementing controversy analysis as a social media method, media studies and STS can be brought into a wider and more intimate dialogue. Insofar as social media research occasions such an encounter between inter-disciplinary fields, some difficult and unsettling questions arise, not least the questions addressed here. However, rather than treating these questions as “distractions” from empirical and technical engagement with social media, or as primarily requiring definitional work (what is your domain of study?), we have suggested they may be productively approached as praxio-logical questions: as methodological issues that can be addressed in and as social media research practice.
This has the advantage of bringing into view the complementarity of different methodological approaches. An instrumental or “precautionary” approach, which is interested in deploying social media analysis for social research, may be especially suited to the early phases of research, when the aim is to craft an “interpretable” empirical object. An affirmative approach may better grasp dynamics that operate across content and medium, analyzing platform-specific dynamics in order to detect issue activity. An empiricist approach, finally, allows us to approach the qualification of the empirical object—are we studying media-technological dynamics or issue dynamics?—as an objective of social media research.
We have only been able to show snippets of the empirical tactics involved, but by discussing how we might move across different modes of inquiry in practice, we have tried to show that social media research offers opportunities for a symmetrical treatment of the relations between media-technological and issue dynamics in the study of public controversy. While this approach is in many ways still to be developed—and while existing contributions to this project are still to be more fully recognized and appreciated—it is clear that by elaborating symmetry in this way, we are not just implementing STS methods in social media research. Rather, social media research invites us to re-negotiate the relations between STS and media studies, and our practice-based account above suggests that practical collaboration is key to this process. It is critical that we do not withdraw into theoretical debates about what constitutes the “proper object” of controversy studies and social media research, but rather look to take advantage of productive confusions between the two.
