Personally, I find entering various parts of the fediverse more fun on broader general instances with fair moderation. Beehaw sounds nice, but also a little oppressive. And in the end, it's still a lemmy instance.
I think it's too early in the post-reddit days to worry about the chaos. Communities/magazines are being built with wild abandon now, but I imagine users will coalesce around a few key ones for each topic. Reddit allowed for infinite subreddits too, but eventually the popular ones took off. There's no rush there, it should settle organically.
I do find it interesting that lemmy, in general, seems to have the momentum over kbin. But again... early days. I'm just glad they are pretty good at talking to each other, though lots of kinks to work out still.
lemmy.world feels pretty good so far to me. Good active local feed, some good homegrown communities that are working to take off, and haven't seen too much drama yet. Good enough for now!
