If you recall reddits growth many of their communities evolved as offshoots of a single generic community. This made it easier for people to see discussions they normally would not get involved in, and once the posts in a similar category reached critical mass it moved to a sub Reddit.
I think people are recreating their niche communities here but they are floundering since the user base is still pretty small. Maybe it’s best to post to the “big” communities until the time is right to move to smaller, targeted communities?
The fediverse should be more resistant to this (I hope). The people in charge of instances are pretty comparable to super moderators since they both can control a lot of internet real estate. The fediverse’s response to bad instance owners is to just switch to an instance that’s run in a way that you like better. Or even better, make a new instance that’s less bad!
If there’s an instance with a problem super moderator, then the same solution should work right? Go elsewhere, or make a new magazine. If there’s a single problem user dominating all communities in multiple instances, well. Time to start “@free.folk” or whatever lmao.
