Author, journalist and entrepreneur Damon Brown (@browndamon) signed up for a 30 minute chat about his new book. We said we'd talk Boston Marathon reporting if we had any time left over. 74 minutes later, we managed to solve the mysteries of social networking, the human brain, and self-promotion.

Damon's really smart and interesting; you should listen to this one.
