Honestly? Still haven't found one.
The communities I've found are all fine, but I haven't found any that are a tailor match for me. Every one so far has either been not quite my cup or a ghost town.
I'm mostly sticking to All and interacting with posts I like as I see them, with no real care given to what community they are from. Individual communities don't have much for me, but all of Lemmy combined holds my interest decently well.
