But that is to understate the problem, because what is really going on here is a clash of cultures. On the one hand are the vast majority of internet users who believe that any life worth living must allow a substantial measure of privacy. On the other are individuals such asMark Zuckerberg, the boss of Facebook (or, as early business cards proudly proclaimed, “I’m CEO, bitch”), who think that being online means sharing your intimate details with all and sundry. As Zuckerberg said last year: “The days of you having a different image for your … co-workers and for the other people you know are probably coming to an end pretty quickly … Having two identities for yourself is an example of a lack of integrity.” He calls this radical transparency. You might call this deeply troubling.
