Thanks! I think comment systems generally (not just HN's) can use a lot of improvement. Better and better sorting algorithms based on recency, user quality, responses to the comment, etc. seem incremental, honestly. It's helpful, but if I were to redesign commenting systems from scratch I would think about the current linear format, whether comments that relate to each other could intelligently be grouped together, etc. I feel like if companies like Disqus and Livefyre are going to compete with the added social value Facebook brings, they're going to have to figure this out and really revolutionize conversations on sites.
