On last day of #aoir2025 @lionw.bsky.social presents our @weizenbauminstitut.bsky.social work on TikTok data donation from the 2025 German Federal Election - only 5% of content was political and the Left party could capitalize most in reaching voters of other parties with their content on TT.

This was a great roundtable, lots of important questions from the audience, giving the impression that data donations will be around for longer, if we get it right (based on comments from the audience on postcards) #aoir2025

How often is too often in ESM research?
🚨New study out!
We compared 6 beeps/day vs. 12 beeps in 2 h bursts.
Both work, but burst designs show more fatigue + attrition — still useful if high temporal precision matters.
App onboarding, though? Big bias alert. 📱

Our new policy paper on #DSA40 explains the detailed processes of data access (with updates from Delegated Act), describes still existing bottlenecks, and discusses the challenges of legal right vs. platform resistance and is asking all stakeholders to act in good faith and to deliver.

In this piece for Tech Policy Press, @dscheykopp.bsky.social , @ulrikeklinger.bsky.social, @claesdevreese.bsky.social and I argue that it's time for regulators, researchers, and platforms to fulfil their roles and standards set by the delegated act on data access.

Tech Policy Press @techpolicypress.bsky.social · Jul 10

LK Seiling, Jakob Ohme, Ulrike Klinger, and Claes H. de Vreese outline what’s needed from researchers, platforms, and regulators to make data access under the EU’s Digital Services Act work.

Time To Deliver: Stakeholder Roles In The EU’s Delegated Act On Data Access | TechPolicy.Press

The Delegated Act on data access under the DSA provides much-needed clarity about both the access process and expectations towards the actors involved in it.

📢 Big news for platform researchers across Europe and beyond:

Today, the @ec.europa.eu adopted the Delegated Act for Article 40 of the Digital Services Act (DSA) – a long-anticipated milestone enabling researchers to request access to non-public platform data under Article 40.4.

dark blue background. on it, there is text saying "The Delegated Act on 40.4 DATA ACCESS is here", "Delegated Act on 40.4 DATA ACCESS" is yellow, the other text is white.

Do Alternative News users also use legacy media? Yes they do, shows a study by @gongbaobao.bsky.social @weizenbauminstitut.bsky.social but a small fraction - around 1.3% of the German population - live in alternative news enclaves

It’s a wrap! #ica25 ends for #DigitalNewsDynamics team @weizenbauminstitut.bsky.social with presentation by Felix Gaisbauer, showing that the more people use alternative news media, the more they share them, but still have the highest fear of reputation loss as reason to not share alt news
