Social networks need critical mass to sustain themselves.
Part of that is making sure this site has that critical mass by encouraging folks to come here.
Part of that is making sure bird site isn't a place where you provide free content anymore.
There's a good chance when you joined here, you cared more about the first of those as a hedge against bird site dying.
But if recent changes mean you want birdsite to affirmatively die, you'll need to do both.
@RobinBrenizer For the most part, no. You can follow people on any server.
There's some edgecases where being in a neighborhood with people with similar interests is a good idea, but you can move later if and when you spot where all your friends are and if that becomes important to you later.
Your followers and who you follow copies over to the new site, although you'll lose your old posts (tho posts are relatively ephemeral anyway so a good chance you won't care much about that)
