I looked at Bluesky's AT Protocol from a developer perspective, making some comparisons to ActivityPub. Hat-tip @danabra.mov, @laurenshof & @pluralistic for work that I referenced. In summary: I think ATProto has a compelling identity and content architecture for developers — tbh it's much better than the fediverse from a personal ID and content ownership pov — *but* decentralization remains a major concern. https://thenewstack.io/blueskys-at-protocol-pros-and-cons-for-developers/
