Definitely. I posted this yesterday in a similar thread about clickbait content:
This is one of the things that I'm struggling with right now as well. My reddit experience was heavily curated in favor of smaller subreddits, to the almost complete exclusion of top subreddits. The thing is, since Lemmy is so new, it hasn't had the opportunity to build up a diverse array of specialized communities the same way. So basically right now all we have are mainly versions of the "big" Reddit communities, along with ones that decided to emigrate here from Reddit.
But it turns out, content from "big" communities is often the same low-effort, lowest-common denominator stuff regardless which platform is hosting it. Memes, clickbait, and ragebait permeate the top results, because well shucks, that's what people want to see and engage with, apparently.
I'm hopeful that if/when Lemmy continues to grow, that it'll become home to more active specialized communities. In the meanwhile, I've been trying to improve the experience as much as possible by A) trying to subscribe to more communities and B) slamming that block community button like I'm playing Hungry Hungry Hippos.
I think it boils down to the fact that a smaller userbase is going to naturally gravitate towards lowest common denominator content because there isn't enough critical mass to form niche communities yet. It's low-hanging fruit to post an angry meme about Reddit, since people being angry about Reddit is why Lemmy/kbin suddenly have so many people. But of those, how many want to talk about inflatable kayaks or vintage calculators?
As far as finding new communities, maybe this page will be helpful.
