Fediverse

Discourse now supports ActivityPub as a method of accessing posts, and we’re testing this out with the General > News category and our announcements. You’ll be able to find out about Mastodon posts and even reply to posts from Mastodon and they’ll show up here!

Most instances have a community where users can request the moderator role for inactive or unmoderated communities.

Context: this community has flairs now! (also, PieFed recently added flair support! - they don't yet federate though, particularly with Lemmy that is lagging behind in features by comparison)
