Discourse is a forum/Q&A hybrid.
Discourse markets itself as a concoction of the good collaborative environment of old-school forums, and the interactivity of modern websites. It's also open-source, you can run a Discourse forum of your own.
Discourse also offers hosting for a very hefty price (~$100 per month). As such, it's very possible that anyone who's using their hosting for their forum could chicken out at any minute, meaning their forum is incredibly volatile. See the Known Victims section for further details.
Scheduled to go read-only on 1 January 2020, migrating to GitHub Discussions.
