Mike Walsh, CEO of Leverage Software gives a great presentation on Ambient Discovery and Awareness at the Inbound Marketing Summit 2009 in Dallas. Out of all the presenters, I'd say Mike had the coolest looking slide deck, which consisted of a bunch of handwritten slides. Unfortunately, I could only get the first 20 minutes of the presentation, as the battery on my Flip Mino HD died part way though. This is a great listen/view, if and when you get the chance!
