p.s. You can usually see a server's Local feed by going to its website and clicking on "Local" or 👥 . You don't need to be logged in or a member. (Some servers keep their Local feeds hidden from non-members though.)

Some third party apps such as Fedilab and Subway Tooter on Android or Ice Cubes on iPhone/iPad let you follow other servers' Local feeds, though of course you need to be a member of the server to contribute to the feed.
