I wrote about Clawdbot/Moltbot/OpenClaw and Moltbook, the fascinating, weird and sometimes even useful social network for digital assistants to swap tips and gossip with each other simonwillison.net/2026/Jan/30/...

Moltbook is the most interesting place on the internet right now

The hottest project in AI right now is Clawdbot, renamed to Moltbot, renamed to OpenClaw. It’s an open source implementation of the digital personal assistant pattern, built by Peter Steinberger …

In 2025, as Bluesky grew from 25M to 42M users, we took actions to keep it welcoming, using proactive design to reduce toxic content by 79%. Our 2025 Transparency Report shares how we're building a safer platform while keeping a transparent and human-centered approach: bsky.social/about/blog/0...

2025 Transparency Report Overview - Bluesky

In 2025, as Bluesky grew from 25 million to 41 million users, we improved the trust and safety infrastructure to better enable our mission. Here's what that looks like in plain language.

AT Protocol, the infrastructure powering Bluesky, “represents one of the most concrete opportunities for Europe to create their own social networking infrastructure,” says Dutch data analyst Laurens Hof (@laurenshof.online).

Here are four case-studies on European projects that give us hope:

Bundestagswahl 2025 Social Media Data Collection – First data release
We are happy to present the first data release in the context of our Bundestagswahl 2025 social media data collection:

Johannes Breuer @johannesbreuer.com · 5d

Thx for the clarification 👍 People use reposting, commenting etc. differently and that's not always clear for everyone at first sight. Then I simply got the message in your post wrong. Sorry!

Johannes Breuer @johannesbreuer.com · 5d

And apologies if I misunderstood your post! I thought the "something to be proud of" was about the person who wrote this particular post.

Johannes Breuer @johannesbreuer.com · 5d

It's still individual people who choose if or how to use such a tool. But combined with the perverse incentive structure in science, the release of such a tool is risky (to put it mildly). As Raphael Wimmer also writes "I fear that it pushes even well-meaning researchers in a dangerous direction".

My colleague Kevin Munger asked me and a bunch of editors to sit and think through AI and peer review. Our take:

We envision an increased (!) involvement of humans in the evaluation of social science.

If you haven't watched the video abstract about Veronika the tool-using cow, you really should, especially the message from her owner at the end! It cleanses the timeline a bit.

Flexible use of a multi-purpose tool by a cow

Osuna-Mascaró and Auersperg report flexible, multipurpose tool use in a cow, expanding the known range of mammalian tool users and underscoring overlooked cognitive capacities in livestock.

I fully agree with this being problematic. However, the poster whose name you redacted meant this as criticism. It is, indeed, not something he is proud of.

Sehr cool! Herzlichen Glückwunsch!
