Just finished Seth Godin's new book called Tribes. Seth says a tribe is a group of people connected to one another, connected toa leader, and connected to an idea. He focuses on tribes as communities and how the Internet is changing the way individuals can lead the world into the Information Age. Seth gives many examples of people chainging their organizations from the inside out. This bottom-up approach ties with your idea of a field led association as an agent of change. I found it to be an interesting perspective about community building as well as an interesting approach to catalyzing change in any organization. I recommend the book for those interested in leadership and the need for it. SteveG
