Berger does a great job of breaking down the various elements that when working together, create a contagious effect. He then provides a recipe for maximizing the chance that your initiative will be contagious. Super narration and fast listen.
Loved the book. It changed the way I think about the media and how I plan on approaching bloggers in the future. Not that I plan on creating fake email accounts but recognizing their mindset and finding a way to give them what they want is invaluable. I thought I was doing that already but after listening to the book, I recognize that I haven't been.
