"Trust Agents" is one of the seminal books in the Social Media genre. So many other authors have copied Chris Brogan's approach to discussing Social Media that he has been elevated to one of the chief "Gurus" along with a few others that include Interactive Media "thought-leaders" Brian Solis and Seth Godin.
In this book, Brogan sets the ground rules for Social Media engagement. At the root of all relationships - on line and off - are trust, authenticity and respect for audience wants and wishes. The goal of all of this is to establish integrity and reputation. The author goes on to explain what the ground rules are for using Social Media; rules that lead to strong relationship building and marketing success.
