I just don't think there's enough active userbase for that, and it really isn't something you can fix on the fly. The ratio of Like/Upvote > Share > Comment > Post is always an issue for online social spaces, its just that a few website got big enough to make it seem like its easy to get people to contribute.
The architecture of Lemmy is also a little bothersome at times, especially when it comes to displaying media and making gallery posts.
Probably one thing I'd like for LemmyNSFW to have is a Admin owned community for people to share communities and talk about merging, managing, sharing, etc. Something like https://lemmy.world/c/newcommunities but for our side of the pond, and now just for new but also talking about present communities and what can be done for them.
