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.

Starting up a Web company is never easy, but at least it’s not as expensive as it used to be. Instead of buying and maintaining an IT infrastructure, as they had to do in the dotcom boom, startups now turn to cloud server services like Amazon’s. Instead of costly proprietary software, OpenOffice and Google offer cheaper (or free) options. Instead of paying office rent, employees can work from home. And the viral power of social media can bring new customers with little marketing. Open-source projects and the durability of Moore’s Law promise to lower costs even further.
