At this point I think ActivityPub has become the social-media-super-glue-protocol it aimed to be. Wikipedia entry of "Fediverse" only lists its own predecessors as not supporting/planning to support ActivityPub.

ActivityPub *is* the "Fediverse", if we don't include things like mail, Matrix and XMPP.

…oh, and then there is Diaspora. The Facebook-Killer. Remember that one?
