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.
What’s to stop .world “defederating” and cutting all the new users off completely.
It’s an odd platform and one that feels like it could all fall apart to someone completely new to it all.
