Some folks have gotten themselves together as something they’re calling the Social Web Foundation, and I’ll cut to the chase: this is an attempt by ActivityPub partisans to rebrand the confusing “fediverse” terminology, and in the process, regardless of intent, shit on everything else that’s been the social web going back twenty-five years.
The Fediverse is a terrible name that only pushes people away. I’d welcome the change of name.
However, the Fediverse was never just about ActivityPub either. The old GnuSocial protocol ActivityPub is based on is also part of the Fediverse. So is XMPP and I suppose by extension Matrix. Like it or not, ATProto is part of the Fediverse too, even though most Fediverse software doesn’t speak it. Services can speak multiple protocols, they don’t need to restrict themselves to just ActivityPub.
ActivityPub folks are probably the largest group of people actually developing an interoperable social media network, though. ATProto is federated but small servers don’t stand a chance against the Bluesky firehose (hundreds of gigabytes of content per day on bad days!) because the protocol is based around “large servers talk to other large servers”. Other federating protocols simply don’t really care much about activism anymore.
Nobody is taking the “social web” away from your IRC channels and your NNTP news groups and your SMTP mailing lists. You can still call them the social web. And frankly, it would be wonderful if more ActivityPub services would speak NNTP because both share the same goals. “I also used to have a social web” doesn’t conflict with “ActivityPub is part of the social web”.
