Can someone explain this like I’m an idiot (because I am)? This sounds like at some point I’m going to need to create a new account because shit will get too….popular? Dafuq? I downloaded Voyager, spent a bajillion hours looking for communities to add to my feed because fuck Reddit, and this conversation is scaring/confusing the shit out of me.
.world was having trouble because it grew really really fast (like it's only existed for about six weeks at this point), and the Lemmy software had never been tested with the sorts of numbers we very suddenly saw during the Reddit migration. So naturally there were performance problems, as nobody had ever run a Lemmy instance that large.
A few instance admins put their heads together and figured out various fixes and optimisations, and now it's running fine. Maybe we'll get into more issues down the road, that's just the nature of being the first to try something new. But it's nothing to panic about, think of it more like you're a brave pioneer into an exciting new world :D
