I’m looking for something where I can do some local community building, I’m guessing mastodon might work but I think the ideal is something like facebook where I can join a group tied to a common idea and a location, as well as being a bit more personal. Is there anything like that?
I think that would be friendica. I haven’t tried it but it uses the ActivityPub protocol so you should even be able to interact with lemmy and mastodon.
