This is exciting and we have been able to read it in the fediverse report number 16: «Work is starting on a protocol bridge between ActivityPub and the AT protocol (the protocol used by Bluesky). Here is a work in progress (and another demo), and also there is a group network starting up that is dedicated to this. This is one of the key stories in the fediverso right now, with massive implications going forward. Bluesky has a lot of energy and interest behind it. of it currently, and being able to interoperate with the rest of the fediversos would be of great benefit to all parties.»
