Part of the problem is there's a lot less to it than it feels like there is. The analogies we use to teach to non-tech people don't quite match up.
It's simply a structured way to log in and send messages back and forth.
You can use it to stitch together forums, link shares, social media, video sharing, or image sharing sites.
But we really don't bind things together all that tightly. At best you can follow someone on pixelfed or mastodon. Since there's truly no minimum wiring, a lot of services don't even really fully communicate with each other. So we end up mostly with mastodon <-> mastodon links and lemmy->piefed<-lemmy links.
activitypub is a protocol. like email.
instances are just what provider you want to use, gmail, hotmail, outlook, etc.
and the 'platform' lemmy, piefed, mastroton, pixelfed, is just the aesthetics
