Following an announcement on Gmail that was apparently not an April Fool's Day hoax, Google got back down to business. Specifically, the business of pricing. The search provider said it will change the pricing structure on the ads it places on partners' Web pages

"Google Gets the Message, Launches Gmail." At first glance, the headline seemed well, like a joke. It's April Fool's day, after all. (I'm still waiting for my colleagues to fool with me).
