Contagious: Why Things Catch On written by Jonah Berger is a natural next-step for readers who enjoyed Maxwells Tipping Point. While the writer did not definitively answer the question posed within the title, the anecdotal style was helpful in developing a higher awareness and perspective going forward. A bit repetitious, the book probably should have concluded about two-thirds of the way. However, worth the read if you are looking to re-position a community or business.
