In a semi-related vein, let me reference my own Ask HN from last week: http://news.ycombinator.com/item?id=1975950 http://news.ycombinator.com/item?id=1975950 My claim was that HN should bake in a "dup" button that let users flag duplicate posts, not with the goal of removing dups, but with the goal of cross-referencing them (and possibly sharing karma or some other idea). I won't recap the whole thing here, but I find DupDetector an interesting complement to those ideas.
