I just attended the "ActivityPub Based Forums and Threaded Discussions" call, and I really like their work on standardising the way, how forums federate.
Thanks @pfefferle! All I did was implement the protocol as many others have done. Half the credit would go to you as well for the other end of the integration!
It is really cool to be able to follow a blog from a forum. Are comments from the fediverse integrated?
