I've been a lot more active on Beehaw over the past few days than on Reddit. Tried to get into Kbin but the servers have been remarkably unstable and I don't like the fact that you can only view 25 comments at once.
I think a lot of subreddits will fold. Your typical reddit moderator is hungry for power and having that power taken away from them is probably more terrifying to them than losing Apollo/RIF/BaconReader/Sync/Relay.
