…  the Bluesky team and I published a paper that’s a bit like a long blog post in PDF format. It’s called “Bluesky and the AT Protocol: Usable Decentralized Social Media”; it describes the architecture and of the Bluesky social network and the underlying AT Protocol, and more importantly, it explains the rationale of why things are designed that way. The paper is a result of me advising the Bluesky team over the course of the last two years.

Social media requires lots of difficult choices, because humans are complicated, but I believe Bluesky does a really good job of balancing the trade-offs. It’s also getting quite popular, having just jumped from about 3 million to 4 million users yesterday!
