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.
Making it difficult for people to abandon reddit and join lemmy at THIS stage would be a bad idea. I think it has to scale.
Eventually if it successfully catches on and becomes the popular option, maybe. But even then I think I’d prefer a (or several) round-robin type options for joining. I think the server names are too exposed in lemmy to be easily understood by the masses. Like I get it but I’m a 20 year dev. Not a person in my family understands.
