The final speaker in this ICA 2024 conference session is Megan Brown, whose focus is on the impact of the closure of the Twitter API on public-interest research. The discontinuation of Twitter’s Academic API was announced in February 2023, and remaining APIs are priced exorbitantly and outside the reach of publicly-funded researchers; this has severely affected any further research on the platform.

Twitter research had been growing steadily since its inception, and was researched more than its use amongst ordinary users perhaps warranted. The present study explored the consequences of the API closure through a survey of social media scholars …

The next speaker in this ICA 2024 conference session is Tian Yang, presenting a comparison of the visibility of news on the Web, Twitter, Facebook and YouTube. Platforms are now central to the presentation of news production, dissemination, and use, and access through social media is considerably more common than direct access to Websites.

But the social media ecosystem does not replicate the web ecosystem, and some news outlets are making better use of those ecosystems to attract audiences than others. Users’ choices of platforms, and news outlets’ choices in engaging with platforms, both affect the formation of platform used …

The final speaker in this ICA 2024 conference session is Ori Tenenboim, whose interest is in why news users limit their public expression online. This might be driven by perceptions of the visibility of their news engagement, and of the consequences that such visibility may have.

News engagement plays a crucial role in democratic life, and plays a role in what people see and engage with; if users self-censor such engagement then this also affects what other people see in their digital media spaces. Non-engagement may also relate to relationship management, and be affected by users’ privacy calculus about their …

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?

This project worked with the Twitter bios of such news-sharing users to determine patterns in their identities; it drew on some 400,000 tweets from 2021 (that were still online, from …

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. This also generates visibility and amplification for their content, as well as engagement metrics for the political actors themselves.

Such uses are also constrained by …

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? What are the themes and strategies of such sharing?

This study gathered one year of data between March 2022 and …

p>The final speaker in this ICA 2024 conference session is Frederik Henriksen, whose focus is on the transformation of far-right political activities on social media during the COVID-19 pandemic. The far-right shifted the focus of its activities during this time, and joined forces with other anti-systemic actors, particularly pushing mis- and disinformation on the pandemic and the health measures implemented by governments to address it.

The present study sought to identify these discursive shifts in response to the pandemic, amongst far-right actors in Austria, Germany, Denmark, and Sweden and across multiple social media platforms – Facebook, Twitter, Gab, VKontakte, Reddit …

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.

Baoning’s work explores the opportunity structures of these three platforms for far-right movements, then: the specific configurations of technological communicative, regulatory, economic, and user …

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.

This is a useful case study of polarisation in public debate, and Gregor studied the dynamics of this …
