If privacy is such a problem for some it is not a technological problem, it is a political problem. If so, people concerned should make their revolution in an appropriate place: the real world, and let internet stay a public media.
PS noticed another fun topic there are blacklisted keywords on HN, like F words. Isn't censorship more concerning than privacy on a media? And funnily enough all the "lite" censorship nowadays are first about sex and gross words. Are sex and slang that dangerous?
