One great pleasure of Davos and DLD this year was hanging out with uber-blogger Jeff Jarvis.

He has a great sense of humor, outlook and fantastic new book that I read on the flight back to Hong Kong: What Would Google Do?

In his book, Jeff does an intellectual road test of what a variety of industries would do, if invented from the ground up by Google.

This is a photo taken by Jeff in Davos of just such a concept, advertising supported toilet paper. The next stage should be individually targeted advertising supported toilet paper. Install a dot-matrix printer in each stall and you’re in business, so to speak.

Not convinced you should buy the book? Check out this video interview of Jeff about his book.

Disclosure: I just signed up to the Amazon associates program, so I would get a small amount (15%, I think) if you buy the book. I wonder how much Jeff makes on the sale of each book. I imagine it is about the same, but he did a lot more work.
