To support decentralization and spread, should lemmy.world close registration at some point to prevent a performance overload due to too many users? Of course, if registration is disabled, there could be a hint placed somewhere near that from other instances you can interact with content on lemmy.world just like you had registered on it. There could be a link to join-lemmys instance overview.
I get the point, but that limits the users’ right to select which community they want to join. I feel that is more important than preemptive decentralization of content. Hopefully there is a way to migrate communities from one instance to another. Should an instance get too large that would be a good feature to mitigate risk.
