Presumably you have never had the experience of being a dissident, fleeing an abusive situation, or simply being embarrassed by some of your friends or coworkers. Or, say, being a grade-school religion teacher who wants to have a sex life. Or being a counselor: Psychological counselors are explicitly forbidden by professional ethics from interacting with their clients outside of work, for very very good reasons; how this will play out in the era of ubiquitous Facebook will be... interesting. I wouldn't be surprised to see counselors adopting pseudonyms, if not actual disguises. I believe it was Danah Boyd, among others, who pointed out that it's much easier to believe in the one-identity theory of humanity if your identity is that of a white well-off Ivy-educated professionally-successful male American. It's certainly a description that fits Eric Schmidt and Mark Zuckerberg to a T.
