Fwiw, lemmyverse.net is a way better community browser than the one built into a Lemmy instance, which often is missing tons of communities.

My experience is that browsing lemmyverse, I find WAY more interesting stuff than what pops up on the all/local feeds, which is generally dominated by "frontpage" style mass-appeal communities that are very general and memey. All the communities I enjoy the most are too small to make the scroll and were find explicitly by searching. I now enjoy my subscribed feed much more than all/local.
