Gaming, news, tech, general literature. All of these are somewhat thriving, with a steady influx of posts and comments. At the same time, the userbase is sorely lacking for more niche communities. In my case it’d be stuff like poetry, yoga, religion, linguistics, meditation. Or many other communities I’d doubt they’d form a larger userbase here, at least to the degree that it’d foster good discussions. Communities where there are a larger amount of “normal people”, that are not tech-aware, and who have no interest in migrating off centralized corporate solutions. That just want a large space to discuss what they’re interested in.
This for me at least, makes it hard to completely leave reddit (or even Facebook and their groups!). Do you think the fediverse will ever reach the point where this would become a non-issue?
I’ve seen some magazines put a note in their description that the owner is willing to hand it off to the mod team of the corresponding subreddit. I think that’s a decent compromise in order to welcome the old subreddit to migrate over and maintain continuity, while also not waiting around for other people to act.
I would suggest using great care in accepting new mods coming from Reddit. Do look at their history with their community and what they shaped the community into.
