I enjoy it so far, but I am noticing that the userbase is currently a lot smaller and thus there are fewer posts and comments. Also, the niche interests are very thinly represented. For instance, I enjoyed following the valheim subreddit to get up to speed with updates and see fun creations. Lemmy has basically no community for valheim. The same goes for other narrow subjects. I expect this to grow along with the popularity of Lemmy, but it's currently a bit shallow.
Yeah, I'm finding the same for things like /r/GayBrosOver30, which attracts more mature discussions than a lot of the other subreddits for gay men. Same with city communities, hobbies, and so on. That said, Lemmy has really only hit its first growth spurt. It's perhaps good that it takes its time.
