A "traditional" UI for HN would surely look a lot like Usenet newsgroup readers. I think Thunderbird might even still support NNTP.
Usenet had a much better model for discussion groups/forums like HN in my view, though crucially for the modern world it is missing some kind of "comment voting"/user-driven moderation. I wonder if there's an HN<->NNTP gateway around somewhere?
Voting could be handled with comments with specific content - wouldn’t even need to have a body, as everything could be in the headers. Totals could be computed at the server, unless we wanted real NNTP-style distributed discussions.
