Going against the post’s spirit, but…If you’re not finding a community for your interests (or only finding abandoned/inactive ones), and don’t want to create one (or try to get existing ones going), you’re welcome over in !general@lemmy.world. Post about whatever, find likeminded folks, then if ya think there’s enough of ya, you can make a separate community without it being one person posting into a void.

Also there’s !justpost@lemmy.world. Similar vibes.
