One Degree Gives Me The First Degree

It was not quite the first degree, but I got an email from Ken over at One Degree. He writes:
“I’ve started a new feature at One Degree called ‘1.5 Questions.’ Every day (or so) I ask someone in the industry one question (and a bit) via e-mail.
Here’s your question:
If you could recommend one book to people interested in how marketing is changing, which one would it be and why?
(See why I call it 1.5 questions?) :)”
If you’re curious as to what my answer was: 1.5 Questions For Mitch Joel.
