Hi, they aren’t. I browse by Hot on All or Local specifically to discover niche and active communities. The memes I see on Lemmy are actually higher quality compared to Reddit, mostly due to the older user base here. Bonus points that we don’t have extremely toxic communities like dankmemes yet. So overall, that’s much much better for me. Even if the content was dog water, I’d still be happy about the absence of toxicity and everyone enjoying a semi-lame repetitive joke.
Yep, I'm jaded in my expectations knowing what Lemmy was prior to the massive expansion through June and July...
It was still a fun place, but it was a couple dozen posts a day across all servers, by a handful of people from the bigger servers.
We still have a lot of fixes to make on Lemmy, especially on the moderation, management, and content filtering side of things (though apps have been thankfully filling the gaps on some of these issues). Niche communities still need more participation to get off the ground. I'll see again where we are in a few months from now.
