I think I would be unwilling to create that subreddit myself, but I’d join it if it existed. I don’t really expect it to succeed very well, though my tentative guess is it has a better chance long term than either discourse or kbin.
(I’d also like to hear how people who voted to stay closed would feel about this. Like, would that feel like a betrayal/defection/something like that, or not? I’m not saying that someone who wants to create the subreddit should necessarily let a close-voter veto that. But it seems good to hear their perspective regardless.)
