I gave you a curt answer; I apologize.
I can go into a bit more detail about Google Buzz. The best way to describe it is kind of taking the functionality of Twitter, public updates—or private updates for that matter—and integrating that into Gmail. The way that was launched provided some very negative feedback from our users and resulted in lawsuits. By the way, we changed the launch procedure within 48 hours of the launch of the product, realizing we'd upset people. We didn't, though, disclose people's personal information without their consent. The product had a bad user experience, though, at launch, and we corrected that immediately because of an outcry from our users. This is similar to what I've described before, which is that we are attentive to what our users care about and we want them to like the products, and when they don't like a product we want to fix that.
