David Hussman is the mind behind devjam. Well known at agile conferences, he also goes "on tour" with No Fluf Just Stuff. Lots of experience with user story writing, coaching and coding. I have seen him sitting down and pairing on a FitNesse test with a coworker. His presentation style is awesome. Watch a couple of his videos to see what I mean. A very nice guy. I am glad he got recognized.
