Comment on Scientists move to Bluesky, transitioning away from X and Meta platforms

Why is ActivityPub “the” Fediverse? “Fediverse” is very broad and encompasses multiple protocols.

The original Fediverse apps are still around and don’t use ActivityPub. For example, StatusNet / GNU Social use OStatus and Identica uses Activity Streams / ActivityPump (which was the protocol before ActivityPub). diaspora (if it’s still around) used its own protocol too.

Because a fediverse is any group of technologies that talk to each other via a common protocol. In 2025 that’s ActivityPub and has been for awhile. It would be one hell of a stretch to assert that a single platform with its own home made protocol that doesn’t talk to any other technology in the entire fediverse as part of that fediverse. So at best you can say Bluesky has its own fediverse. And if one fediverse is going to be “the fediverse” it’s going to be the one that actually connects all the most common platforms people use today, including Diaspora.

  Diaspora doesn’t use ActivityPub, does it? It’s still a Fediverse app though, and still fairly widely used.

  I agree with this.

    Oh, looks like it doesn’t. It’s Friendica that uses both ActivityPub and Diaspora protocols
