Can someone point me to a good technical 101 for Mastodon? Or OStatus? Trying to understand: When I make a post, how does another instance find out about it to show to my followers there or the federated timeline?
So I think it's the PubSubHubbub portion that does what I'm looking for.
Current understanding: I make a post & my instance pushes that post to each instance where someone follows me.
Which means if some single-user instance's user follows me, but no one on my instance (including me) follows them, then my instance is "aware" of theirs, but not in a way that their posts would show up on our federated timeline.
Anybody poke holes in that?
@NthTensor Middle thing reworded and still correct: No one on my instance has asked for posts from the single-user instance, so my instance never subscribed to them on the single-user server and thus the single-user instance doesn't push them to my instance?
Third thing: Yeah. Good clarification.
