In this age of facebook and other social networking sites we are slowly but surly loosing our privacy
Here is the interesting quote from Eric Schmidt ex CEO of GOOGLE
Schmidt told the Atlantic at the Washington Ideas Forum in October 2010. He went on, speaking about the future of search,
With your permission you give us more information about you, about your friends, and we can improve the quality of our searches [...] We don't need you to type at all. We know where you are. We know where you've been. We can more or less know what you're thinking about.
