Suppose there’s this site I really like, and I like the fediverse, and I think it would be awesome if they joined the fediverse, to benefit everyone involved. Is it like how it was in the Zorro movie where they vote California into the US, Zorro swipes all the voting boxes with a Z, and everyone cheers, or is it not possible for just any random schmoe site to join?
the site would need to implement the activitypub protocol
it can get very complex, but it depends on how interactive they want to be.
