This make so much sense! I'd add a "replied" section too, to see hall the threads one has been active responding, and another filter could be “zapped”

What are your biggest UX challenges using StackerNews?

Some thoughts on what could be cool:
- one could 'follow' or 'subscribe' to particular posts of interest and some mechanism could be available to see a list of new comment threads for that post.
- posts could have some useful properties, similar to how email clients manage received messages:
  - seen, read/unread, save/bookmark/star, etc
  - there could be check boxes to filter out posts based on said properties

These are just some ideas.
