I have accounts on a few different communities. Mostly because there is no real way to know how the community is until you start interacting with it and it starts interacting with with other communities.
Beehaw is nice because they are actually trying to cultivate a friendly community and moderate a lot of the trash out. But also... sometimes you dont want that hand holding...
The biggest benefit I see so far is the lack of bots. I know there are still some bots out there but most of them are useful bots and not just karma farming bots or bots designed for propaganda.
