Ya know, as someone mentioned, some parts of Usenet are still pretty good despite all the attacks. Same with some parts of reddit despite Spez (I don’t post on reddit any more but I still lurk sometimes). Other than that I’m sometimes on a few niche forums mostly related to nerdery. For technical reasons (i.e. because of some not-great software decisions) I don’t like Lemmy all that much, but the community is ok and the implementers’ hearts were in the right place.
