Very much enjoying this one. The three rules of epidemic: law of the few, stickiness factor, power of context.
Law of the few: connectors, mavens and salesmen
Paul Revere was a connector (one who is charismatic and knows a lot of people) and a maven (broker of information). Hence the revolutionary war.
How ideas tip into the majority, from being thought up by a minority of innovators. Highly recommended.
