I would give my left arm to be using internet forums again. Online communities adopting Discord and Slack was such a terrible move in hindsight.
Definitely rooting for this to take off.
I believe we need to standarize forums api so we can build readers as well to see all the forums you are subscribed to in one place instead of jumping between websites
If you like the old school bulletinBoards + standardized protocol, then you may like LemmyBB. An homage to the classic forums with the reach of activitypub protocol: https://github.com/LemmyNet/lemmyBB
