VB Engage 016 - Roland Smart, vide-no, and the new marketing battleground - The one where we build Google up, then knock 'em back

This week, Stewart and Travis take a massive swipe at the mess being created by Google's video calling strategy, the joy being created by Google's app advertising strategy and the sudden death of Blab. We then get to talk with the ever-clever Roland Smart about everything from marketing tech, to mobile, to the battle that's raging between marketers and engineers.
