Burson-Marsteller’s global CEO, Mark Penn, recently published a book titled Microtrends. The book details the small trends that are generating big change in America. Early buzz from clients and media is very positive. I am fascinated by this thinking, and am especially interested in the implications for digital communications. Given how online communications make the world a smaller place it will be especially interesting to identify personal microtrends. Have a look at the Web site, and send a chapter to a friend.  It will be interesting to discuss which microtrends we all find most interesting.
