Shel Israel, Author of Twitterville

We're lucky to have a number of esteemed guests join me on The A-List, but tomorrow, I've got a biggie... Shel Israel. For the better part of 25 years, Shel has served as a social media expert to companies and individuals through his best-selling books. His latest, Twitterville: How Businesses Can Thrive in the New Global Neighborhoods, takes on the subject of the social network that's changed the way so many of us communicate. We'll talk about the inspiration for the book, his career and much, much more. Tweet in your questions and tag them #alistQ.
