Ever met an Evangelist? Even wondered what we do and how we, as Guy Kawasaki states go through the process of "Selling the Dream". Microsoft evangelists were interviewed for this along with evangelists from Adobe, Ebay, Google, Yahoo, Sun, etc. 

 As an evangelism Manager and Director for the last 7 years, this is a very interesting read.

The purpose of this study was to gain a clearer understanding of the relatively new phenomenon known as the “technology evangelist.” By our exploration, we aim to help readers improve their management functions, and to understand how best to integrate “evangelists” within their organizations.
