I pretty much only engaged actively with niche videogame subreddits and absolutely zero of them have made the move over to kbin. I don't know if they'll ever pop up here unless there's another general exodus from reddit. Will the starcraft community move over? Barotrauma? Mechabellum? Monster Hunter?
And what about the niche dumb memey communities like DesirePaths, or toolgifs, or StupidDoveNests? Do those even have a chance of cropping up unless the mods over on reddit decide to unilaterally move their communities over?
I genuinely don't think so, so I'm a little lost right now.
