I first used lemmy on lemmy.world but due to its size I had several issues of things just not loading and needing a full page refresh. So I tried to set up my own instance and it works mostly but the federation aspect is leaving me with a few questions.
Will remote communities only sync new posts from when I subscribed or will past posts show up eventually?
Is having a single user instance realistic or should I try find another small instance?
Essentially it automatically subscribes to popular communities from other instances on behalf of a user within your instance. That way, when you want to subscribe to a community at some point, it’s quite likely that it will already be full of comments already.
