This is the sixth and final column in a series I've been publishing in MediaPost featuring excerpts of interviews I've conducted while writing my book, "Everything I Know About Marketing I Learned From Google," due out this fall from McGraw-Hill. Previous installments included Seth Godin, Rishad Tobaccowala, Scott Hagedorn, Paul Gunning and John Battelle, and 11 assorted marketing all-stars.

Today, I'll share 140-character-or-less responses from 19 marketing gurus regarding the most important thing they learned from Google:
