On the off-chance anyone is trying to look at my personal website, it's currently offline while I migrate to a proper newsletter system. For now, if you want to be added to the subscription list, let me know. Posts coming up on pro-social design and how to predict the future [of political culture].

Today, we will submit expert input to the EU on systemic risks stemming from online platforms and search engines. We argue risks come not just from technology, but also (1) the attitudes of companies and (2) lack of transparency around enforcement. Read our full response here: t1p.de/uoc2y

Just realised Thursday was my 3 year anniversary in Berlin. Pains of migration and bureaucracy aside, it's been an absolutely great decision.

This from @klonick.bsky.social and @reckless.bsky.social was, as per, great. But q: does "the state still has police and jails" apply to the EU/DSA? Eg if a platform isn't following transparency provisions & refuses fines, noone goes to jail, right...? (Durov was got under French law, iirc)

TL;DR - the "Meta fact-checking was negligible" story may be more complicated, from DSA data. This (excellent, must-read) post by @jonathanstray.bsky.social cites @columjournreview.bsky.social and @popular.info low numbers of fact-checks in the USA (somewhere between 10 and 14 per day, in 2020)

I've been exploring how X Community Notes Data might be used for social media monitoring. Found some possibly interesting approaches: in-progress but wanted to share where it's at. When more robust I can share code etc. Please do share with the social media monitoring folks in your life!

Seeing a lot of (interesting and useful!) debate about fact-checkers vs. community notes. But seems to me it would likely be best if Meta did *both*...?

I really, really don't want to do this, but let's do a bit (just a LITTLE BIT) of fact checking about what Zuck said on the Joe Rogan podcast, because this is something I not only followed closely, but also spent time *talking to the actual people at Meta who dealt with this* which WAS NOT ZUCK.

Interesting points from Laura Edelman about the “more personalized approach to political content” part of the Meta announcement, which she sees as a return to political content ranking a la 2016-2020. x.com/LauraEdelson...
