The debate continues on whether CEOs should be fluent in social media or not, but the number of CEOs using social media to engage customers is still very low, even among technology companies.

In the past year it seems that executives have become more comfortable with platforms like Twitter and Facebook. For example, there are a number of influential CEOs using Twitter to represent their companies and bring a friendly face to their businesses. Tweeting CEOs like Tony Hsieh of Zappos and Guy Kawasaki of Alltop are well-known for their successful social presences and large followings as a result.

With all of the talk about how CEOs are getting social, we were curious to see how many CEOs are also branching out into web video. We took a look around the web to see how CEOs and founders are leveraging video to educate and engage consumers.

Once again, we found that the number of executives active in the web video space, as in the social media space, is quite small. But for those business leaders taking an active role, we've uncovered some great successes. Here's a list of 12 CEOs and founders leveraging web video to promote their businesses.

9. Pam Liebman, CEO, Corcoran Group

Real estate pros are jumping on the social media bandwagon, and Corcoran Group, the largest residential real estate firm in New York City, is ahead of the pack.

Corcoran has an extensive social media presence, and their video presence spans to YouTube, Vimeo and blip.tv.

The videos feature CEO Pam Liebman answering questions posed by Facebook and Twitter followers regarding the state of the housing market and New York living tips. These types of videos allow the Corcoran team to truly engage with potential customers, as well as showcase their expertise in New York City real estate.
