@DanDC I appreciate the comments. I agree that my original comments look venting rather than a contribution.

I also standby the fact that duplicates (and not re-posts) are a problem on HN.

By duplicate, I mean the following: 1. Identical domain (such bbc.co.uk vs. bbc.com) 2. Identical url (cnbc.com/ vs. cnbc.com/?click=homepage) 3. Identical age - Submitted within the span of active discussions happening on the HN.

In case of re-posts, despite (1) and (2) points above either the discussions have ceased or mods have permitted re-posting.

Currently, on an exact url match of a previous story, HN notifies the user.

It would be great for HN to detect duplicate stories (not just an exact match). Let the user know of another ongoing discussion. Give an option to resubmit with that knowledge.
