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?
I'm chasing this because someone mentioned the idea of a new privacy setting where your instance would more closely federate with a short list of other instances (forming a slightly larger community). Basically a list of other instances your posts would go to that wasn't Just Everyone in the Federation:tm:. I'm trying to understand how that might work on a technical level and it doesn't sound super hard or breakey.
@benhamill It depends on who runs the servers and how close you want them to be...

You could fork the main code, and create a p2p pipeline between the instances so that all toots from one are assured to end up on the other two...

That only works if the admins of the servers are willing to all use the same codebase.
@NthTensor Nah. 100% solve it in Ruby. If I implemented this, I'd be looking at a PR against mainline Mastodon. I don't want a closed system, I want an inner circle and an outer circle, both.
I think I grok this well enough that I might at least open an Issue to discuss it with maintainers.
@benhamill Tell us how this turns out. I am interested.
@benhamill Anther solution is follow bots; but at that point, why not just implement them directly in code. After all, you want a closed system.

Follow bots are necessary because they allow for extension over the entire network. You do not require that.
