Earlier this year, Seth Godin spoke at part of the Authors@Google series, talking about his book "All Marketers are Liars".
It's worth viewing, downloadable from Google Video as an .avi file.
There are a number of memorable moments and thoughtful quotes to consider. One of teh ones that sticks with me is his view on the misconception of many companies, that "technology is going to solve every problem, [and] the marketing will take care of itself."
That and his experience wearing a Google t-shirt in Manhattan.
