Out of curiosity, is there a HN equivalent to removeddit? There have been situations where I would have liked to be able to see if something had been edited, or look and confirm what the past version of a comment had been.
Not that I know of, but there are lots of third-party HN projects out there.
We've sometimes thought about tracking and showing the edit history of HN comments, but I think this is one place where (let's call it) over-surveillance could lead to more harm than good. Certainly some users abuse editing, but there are also many cases where it's important to let people save face, give them an out, and so on. HN is supposed to be a community and it's important for communities to be forgiving. A certain degree of forgetfulness creates greater ease and freedom. No one wants to be around a superintelligent flaw-pointer-outer. So I think an edit history tracker would have unintended consequences and on balance is probably a bad idea.
