At #FediForum today, we ran two sessions.
The first session brought together implementors of ActivityPub, AtProto/Bluesky, Nostr and IndieWeb applications to discuss how these protocols relate to each other, and what recommendations they all have for potential adopters who need to decide which to support.
It was a productive, cordial discussion and we will have more to say about it once FediForum publishes the notes from the meeting.
