The SBNation article commenting system, introduced like ten years ago now, had a nice take on this. Nested conversations like HN, but with live updating as new comments came in, and tracking of read-vs-unread, and keyboard shortcuts to navigate posts.

That interface + "topic threads" like an old school forum front page instead of "comment just on today's article" would be nice, I think. Let's you chat in real-time when folks are also online, but search and minimize/expand subthreads and such for when viewing later.
