Earlier, I wrote about how not everything on the social web could be reduced to a stream of activity. After spending some time learning about offline-first apps, I've come to realize that Activity Streams provide a nice interface for conflict-free replicated data types (CRDT).
Based on Jack Dorsey's statement, I read a lot into ActivityPub which is mentioned in the replies multiple times. I imagine it's the inevitable standard that the bluesky team will choose as it does fit Twitter's use cases (unless they fall down a rabbit hole of decentralization tech). Although, I'm not convinced that Twitter will become an ActivityPub server, they may only be an ActivityPub client.
