Flushed out niche communities. There was a real push to create communities a few months ago but it seems like a lot of them haven't been getting attention since the blackouts ended and a sizeable amount of people returned to Reddit.
It's understandable considering there's comparably less people. It would be harder to branch off from a gaming community to specifically a Splinter Cell community for example. That said a lot of the communities that were quickly created and seemingly abandoned aren't super flushed out with things like a logo or general information in a sidebar which might cause people to not post there to begin with.
I feel like these communities have a real decent chance especially if they are created in larger instances due to how many people sort by all/new on Lemmy compared to Reddit.
Maybe how easy it was to find posts on Reddit using a search engine? Like Googling "How to care for cast iron pans Reddit"
I don't think I'll miss the avatars, awards, the Redditisms, how much weight people put into upvotes, the sorting algorithms, and so on.
