The idea was to pick a smaller one to spread the load around and stop any one instance (at the time it looked like probably Beehaw or .ml) getting so big it became a "default" and thus accidentally centralising things and defeating the whole purpose of being here.
I guess a lot of people had the same idea at roughly the same time as me though lol, and now we're stuck with some serious unforseen federation issues due to sheer size. Therewasanattempt.
I think I read about future plans for being able to move an account to a different instance? I don't know if that's a possibility but I would be willing to move to keep things spread out, or create a new account if it was necessary. I know a lot of people wouldn't want that hassle but I'm glad to have a forum alternative to reddit and probably enough people feel that way to help make this work well into the future.
I do think that'll be something that gets added eventually but it's understandably not a top priority for the devs right now. I've been through the migration process with one of my Mastodon accounts and it was really smooth so fingers crossed we end up with similar one day!
When I had to move my other account off Beehaw due to them pulling up the drawbridge it was a manual process of resubbing to everything, but tbh it only took about ten minutes once I got a system down so it's more a psychological barrier than an actual timesink.
