@jasperb @sebastian @futurebird @Gargron @dansup @pixelfed Interesting detail from that link: "Mastodon has been developing a built-in groups feature for some time now, but it hasn’t been released yet. From the screenshots posted so far, it seems it will be more of a Facebook Groups type forum rather than a public discussion list. (You can see highly technical details and screenshots of this upcoming Groups feature on their github page https://github.com/mastodon/mastodon/pull/19059 )

"However, it is unclear if Mastodon groups will work across the Fediverse or only on Mastodon. Guppe is platform-neutral, and will work on any kind of Fediverse server that supports microblogging including Mastodon, Friendica and others."

Lots of activity on the Github page around 2022 by @ClearlyClaire but not much since?

Also, there's a video on how it'll work, and this note: "This PR is not intended to be merged outside of purely development environments until it's finished. While it has reached a pretty stable state, groups are a complicated topic, and the database model, API and protocol design may change before the PR gets merged, with no clear migration path between versions of this PR."
