In its early days, social media was considered to be a communications channel that was the sole turf of teens and twenty-somethings, clearly outside the mainstream. But as Facebook, Twitter and myriad other social media sites grow in popularity and influence, it is becoming impossible not to consider these a part of the mainstream of global society.

This is a notion that, apparently, is lost on the vast majority of Fortune 500 CEOs. According to a Fox News story, and research conducted by the blog UberCEO.com, only two of the top 100 CEOs had a Twitter account and 81 percent had no personal Facebook page.

The story and research cites missed opportunities for the CEOs to connect with customers and other stakeholders. It will be interesting to see how quickly these business leaders seize the opportunity that social media offers.
