How would you represent that? On HN and similar every response is its own thread. This is true with email as well, but I don't have experience with any significant threads or mailing lists. The naïve solution would be to just limit nesting and order nested comments chronologically. Another solution may be to CC @postid in your messages and have posts display "responding to: id1, id4" at the top and "responses: id91" at the bottom with appropriate links. There's a question here about which post to write or display your response under. Finally, an extravagant solution would be to really represent discussion as a graph and I think a lot of time would need to be spent creating an interface with minimal frustration as I feel it can get really involved (i.e., a lot of clicking). Curious what you or anyone else thinks.
