We caught up with David Bullock at BlogWorld Expo and got a snap shot of what he had learned from the panel sessions. David is a very smart dude so pay attention to him. I met him this past Spring at Liz Strauss' Biz School for Bloggers and was blown away by his approach to business development. He says he's a newbie at social media, but he's a quick study. David spoke on a panel about how to monetize social media and presented a case study of how Barack Obama is using social media. Check out http://www.barack20.com.
