Connectors, Mavens and Salespeople

More progress on a book called The Tipping Point. He's discussing three types of people that make epidemics spread:

1) Connectors: People who have vast social networks spanning many areas of interest or groups of people. Naturally gregarious.

2) Mavens: People with tons of information and an unselfish desire to share that information. Generally these are the price trackers. They read Consumer Reports. They spread information about a market.

3) Salespeople: These people are able to sell a concept. To push the right buttons. They have a certain charisma that makes this selling of concepts possible.
