The third speaker in this ICA 2024 conference session is Iris Baas, whose interest is in the self-identity of Dutch Twitter users who share the news. Twitter is (even now, following its enshittification) a key platform especially for news consumption in the Netherlands, and who is sharing news on the platform is therefore centrally important. Are there district groups of such users, then – and what news do they share?

The final presenter in this session at the ICA 2024 conference is the excellent Hedwig Tønnesen, whose interest is in the strategies of political actors on three social media platforms. Social media are now widely used by such actors, of course, but have not necessarily delivered the wider democratic potential that some had seen in them; more often, they are simply used by parties to create engagement and mobilisation, or disseminate information and political advertising.

The next speaker in this ICA 2024 conference session is Mengyu Li, whose interest is in link-sharing patterns on Twitter and Reddit, here in the context of the abortion debate in the US following the Supreme Court’s abolition of Roe vs. Wade. Which information domains are critical in this context – health and welfare, civic and activism, political and legal, economic and employment information? How do social media platforms address these information needs? What primary sources are being shared here?

The next speaker in this ICA 2024 conference session is the excellent Baoning Gong, whose interest is in the social media activities of the German far right across a range of platforms: Twitter, Telegram, and Gettr. This cross-platform focus is important because they all form part of a far-right online ecosystem, but single-platform studies still dominant the research literature. Far-right actors are well-known for moving between platforms if their accounts are banned from any one platform.

And the last speaker in this Indicators of Social Cohesion symposium is another local, Gregor Wiedemann, who is applying such Social Media Observatory approaches to the German debate about nuclear power. Nuclear energy slowly began to be phased out after the Fukushima disaster, but this has been challenged in recent times especially as a result of the energy crisis following the Russian attack on Ukraine, and some political actors are still calling for the (technologically impossible) reactivation of German nuclear power plants.

The final session of this very enjoyable Indicators of Social Cohesion symposium in Hamburg begins with our gracious host, Felix Victor Münch, introducing the Social Media Observatory (SMO) project at the Hans-Bredow-Institut and Research Institute Social Cohesion. Felix introduces this as a kind of DIY research infrastructure building effort.

The final speaker in this session at the Indicators of Social Cohesion symposium is the fabulous Annett Heft, whose focus is on patterns and dynamics of conspiracy theories (as part of the Neovex project), and especially on how these spread from the fringes to more mainstream visibility, not least also via social media.

The next speaker at the Indicators of Social Cohesion symposium is Eckehard Olbrich, whose focus is on the evidence for polarisation in the German Twittersphere. This seeks to evaluate the claims about the role of social media as a driver of polarisation, and to address the negative impacts of such polarisation if such polarisation is indeed present. Polarisation might exist at issue, ideological, or affective levels, and these levels also intersect with each other, of course.
