With more than half of the U.S. public on Facebook and more than 200 million tweets sent each day (about 30 percent from the U.S.), American life is continuing to enmesh itself with social networks. But for the CEOs of the top 500 U.S. companies, social networking is a small — if existent — piece of successful living.

In a report released Thursday by Domo and CEO.com, the online presence of Fortune 500 companies’ top executives was compared to that of the general public, revealing that less than 30 percent have at least one profile on social networks. The vast majority have none.
