Johnny Diggz is founder of communication companies Voxeo, Tropo, and most recently Geeks without Bounds.  We talk about the history of Geeks without Bounds, how it was conceived, the role of social media vs traditional media, and how virtual volunteers can help.

We also talk about the ideas and applications that come out of hackerspaces, hackathons, gameification, and crisis mapping.  We discuss the ramification and the ethics involved in the applications, IT departments and of course Zombies!
