Let's say that someone reposts an old Spolsky article that has been around for 3 years and was posted back in the day when it was fresh. Instead of detecting the duplicate and not allowing the repost, I'd like it if HN automatically posted a link to the old discussion as a comment on the new post. Maybe do some sort of filtering on dates, so that the system disallows reposts of recent items as it currently does, but doesn't block posting a 3 year old article again for more discussion. Not everyone was here 3 years ago, and asking someone to search HN for every old article they might be interested in is a pretty crappy interface for discussion. Edit: Removed dangling "There's value in revisiting discussion" statement.
