Query: Ivory Tower Hot Air

This book screamed: "Those that can, do; those that can't teach and write books like this." In a day and age when marketing, thanks to the reach of the Internet, has reached new heights in ingenuity this book is ingenuous and stuck in the 80s. With all the dot.coms there has to be a ton of proven marketing whiz kids who can teach all of us a trick or too. Instead, we have a fuddy-duddy professors who have no experience in today's marketing dynamics and techniques trying to tell us what they think it is all about. Where is the credibility?
