What do you think about Lemmy, so far?

I think it's good for broad, serious/informative discussion but lacking for more niche or casual stuff. Niche is just because there's not enough users. Casual is probably partially that, but also because Lemmy just attracts a more serious crowd. Even the general gaming communities disproportionately trend towards serious discussion of industry problems. And a Lemmy that's better for casual stuff is probably worse for serious stuff.
