To head off any potential accusations of impropriety, ActivityPub.Space is simply meeting ActivityPub discussion where it already is — the fediverse. The same people who post on SocialHub continue to post on SocialHub 🙂 In fact, ActivityPub itself heads off the need for tribalism between forum communities. Both Discourse and NodeBB can federate with each other. NodeBB just has additional tooling that helps soften a bunch of federation's rough edges, plus first-class threadiverse support and discovery features for non-forum content (read: mastodon, et al.) As for questions about which format is best: it doesn't have to matter. Participate on a forum, participate on a microblog, it shouldn't matter because the conversations should be accessible to both kinds.

Check out this intro to HDA (Hypermedia-Driven Applications);https://hda.daz.is/architecture/why-hypermedia-driven-architecture/This seems relevant to the ongoing discussions about C2S APIs for the fediverse, especially the proliferation of the monolithic server+web-app antipattern. If Daz (@daz@social.coop) is correct, properly RESTful APIs that use an HDA architecture might be a way to realise Christine Webber's original vision. Fediverse web apps with specific purposes, like browsing and posting video, as ways to login to generic AP servers hosting general-purpose accounts.
