Dumb and honest answer: do you have an automated tool to generate such a list of "we discussed that already" ? Would it belong "somewhere" in the base UI for HN (if it's ever allowed to change ?) Or do you just keep a list at hand for the usual suspects ?

By using dang's comments I can fetch all historical discussions and render them on the same page. Easy made simple :)
