Social networking might be booming but bosses don't twitter or blog. For good reason too.

A new survey, published here, reveals that only two out of the top 100 chief executive officers in the United States have Twitter accounts, only 13 have LinkedIn profiles, 81% don't have a personal Facebook page and not one of them has a blog. That's hardly surprising. One would imagine bosses would be too busy to install TweetDeck or waste their time on Facebook quizzes.

Indeed, why would any boss want to be involved with Facebook, Twitter, LinkedIn or Wikipedia? As Newsweek points out, people who run big businesses live in a completely different world and for all the hype, they would find social networking sites next to useless.

"CEOs will never come to the social networks in any numbers. Most have enough reputation problems and they do not need those magnified by people who have nothing better to do than go online and insult one another."
