Will Google stay focused on it's foundation of a clean design for the user's searching experience? Or, will Google loose sight of the user and become a page of cluttered advertisement? Hmmm...
So suggest yubrew how such giant company like Google is, should generate income and provide all its services (very good services imho) for free in the same time.
wasn't this blindingly obvious?
eyeball time matters because people who have stuff to sell need people who wish to buy. search/email/maps... are just ways of making your net-billboard the first one people see. finally people are being 'paid' to receive advertising.
