Not really.

The high volume of unoriginal Linux content is getting old, and that's coming from somebody who uses Linux.

Behind that, there's very little in the way of niche communities/interests. But I suppose that's just because the total number of users isn't high enough for people with specific interests to reach some critical mass .

So for me, Lemmy hasn't been anything more than a news aggregator interspersed with the occasional funny meme.
