and they’re not exchanging data, in the sense that if there’s community jimbo on instance rambo, all comments are stored there.
No. The comments are saved by every instance that has at least one user subscribed to [email protected]. If Rambo.com goes down, you wouldn’t be able to make new content but I’m pretty sure everyone else could view what was there.
if there’s multiple jimbos on different instances is there some aggregation type of deal or do I have to subscribe to all the jimbos out there? and if I have something important to say about topic jimbo, I just spam/crosspost my idea to all the jimbos out there?
On Reddit there was /r/tech and /r/technology. One of those became the big, go-to sub.
Same will happen here, just give it a bit of time.
And that only effects outbound federation basically? So a small instance shouldn’t have much issues with this, even if it’s subscribed to a lot of very busy communities?
