@Fragglemuppet Friendica does have Groups but I think they may not be in wide use yet - and if they aren't posting publicly I don't think they would end up in your feed. You can sort your feed for Groups posts in the Account Types menu in the left sidebar (desktop) or menu bar (mobile); I'd probably also sort for Local or Global Community first then select Groups to see what's going. Since the infrastructure is new I don't think there's a lot of niche content just yet, I mostly see news groups.
