The next speaker in this IAMCR 2018 session is Mikko Villi, whose interest is in the reserve of news media journalists on Twitter. There are already a number of studies of journalists’ use of the platform; the present paper focusses especially on Finnish news media and journalists, however.

One key question here is whether such uses are still following mass media logics, or embrace the logics of social media platforms. But the distinction between the two is a simplification, of course; in reality there are sliding transitions between the two, and Twitter’s broadcast-style model of message distribution is …

The next speakers in this IAMCR 2019 session are Gerret von Nordheim and Florian Meissner, whose focus is on the media reporting of digital technology. Such reporting has largely remained dominated by corporate voices, and a previous study has examined how Germany’s Süddeutsche Zeitung has covered tech issues over time.

The newspaper’s coverage of the violation of privacy norms has gradually declined over the past ten years, while datafication has become a more important topic – why is this so? Some of this may be explained by an elite focus, homophilous networks amongst journalists and tech leaders, and intermedia agenda-setting …

The next speaker in this IAMCR 2019 session is Christian Baden, who shifts our focus to processes of polarisation. Some existing work on polarisation focusses on the themes and content along which groups are polarised, but in itself such differences may not be problematic; rather, the key issue here is whether such polarisation is increasing and results in incompatible perspectives.

Homophily and antagonism drive such processes. But homophily is extremely common and not necessarily a problem in itself; some homophily is natural, and it only becomes a problem in extreme situations. The question is therefore whether homophily increases over time …

We finish the sessions at the 2019 AoIR Flashpoint Symposium with our second keynote, by Rebekah Tromble. She begins provocatively by suggesting that we as digital media researchers need to get over ourselves, so this should be interesting.

Many of the current problems for digital media research stem from the Cambridge Analytica scandal, which resulted in the shutdown of many of the primary sources of social media research data – especially the Application Programming Interfaces (APIs) of leading platforms. Most applications for API access to Facebook are now denied, for instance; the Instagram platform API was scheduled for shutdown even …

The next paper in this 2019 AoIR Flashpoint Symposium session is presented by Felix Münch and Ben Thies, and Cornelius Puschmann and I have also made a small contribution to it. Our project adapted an experimental algorithm to sample a language-based Twitter follower network, and this was necessary because gathering Twitter follower networks at scale has become increasingly difficult.

Information on such follower networks would open up significant new avenues for investigation that cannot be answered by examining actual interactions (via @mentions and retweets) alone. We did some such work in the QUT Digital Media Research Centre by mapping follower …
