Suggestion: the Rerun button allows veteran users to signal that an article has reached the front page before. Far from flagging the links for removal, the rerun button signifies that the content has a timeless quality.. it definitely isn’t news, but it is still worthwhile. A link that is getting both sufficient upvotes and rerun clicks is moved to the Reruns page, which would feature all manner of old chestnuts and stop them clogging up the front page.

I really don't think that duplicate content was ever a problem for HN. It's just not an issue.

The community has done a very good job of providing links to earlier discussions and has generally accepted that occasional repeats of old content are nothing to get worked up about and may even be desirable.

I agree. Though I'd like something to address duplicate submissions within a small window. Like the double front-page stories of bing's 30% market share...or the double ask-page entries on the new karma-less comments.
