I find your comment to be idiotic at best. Sorry to go off like that, but by your logic people who condemned Dr Mengele are being judgemental (sure I know the crimes are not nearly at the same scale). The fact that you find this interesting or fascinating (and it is a moot point whether the observations are really contributing anything at all to human knowledge) is completely besides the point. I don't understand how some HN readers wouldn't think 2wice about condemning what the NSA does (which has some justification and would be really fascinating if we could all see it) and think of giving this a pass (presumably since it did not involve your own privacy).
