@QHC I'm chugging along here trying to get out at least one "thread" per day, though I've been ignoring the Microblog posts. Nothing significant has coalesced to my knowledge, or I'd bail on where I've been posting to go there. Seems there is a fairly small overlap so far for people annoyed enough with Reddit to leave and die-hard cfb fans.
https://lemmy.world/c/cfb has a few hundred subscribers and some traffic. Technically it's more active, but not by much. Still, I might eventually do any posting over there.
https://fanaticus.social/c/cfb is trying a different tack and being a properly "focused" instance for sports, but so far they've just been bot-posting the /r/cfb threads. It might blow up, but frankly while I'm not commenting there anymore, if I want to see what's on reddit, I'll go see what's on reddit.
