Otherwise, if we have a lot of medium sized instances but the most popular communities are hosted on just a few huge instances, doesn’t that defeat the purpose of distributing load across many instances?
If that’s the case, how do we solve the cumbersome user experience of having to subscribe to the same community over and over again across a ton of medium instances?
Federation is the key. If I’m on A and I want to see B, A just needs to federate with B.
Does that mean that a community on instance A acts like it were native to instance B?
They’ll see each other in “all,” but not “local.”
