Hey does anybody know if there’s a description of ActivityPub available that isn’t just the spec? I realized I don’t actually know how the protocol works, and I’d be interested in learning more. May have to just bite the bullet and dive into the spec – it doesn’t actually look too bad based on a quick glance – but a summary would be cool
The overview in the spec is probably as good of a summary as anyone could give you.
Another commenter had this to share, it’s got a bunch of guides etc.
