There are things I don't like about Lemmy, but they are minor, not much of an issue. I don't understand what good federation does here, but it does no harm either. It's very light, I love that aspect. I tend to prefer traditional forums, but not all of them are good. Some are terrible, like they're trying to kill off forums, hahaha!

But for me, personally, Lemmy satisfices, and it's already in place.

I have tried Matrix once, didn't like it. Could change my mind about that. But what would it be like? I need some structure, and I'd probably run away from something more chat-like.
