This is a little too creepy for me: Did you know that Google is developing software that "listens" to sounds in the background of your home? It says so right here. Yep, that right. Using PC microphones they will be able "listen to whatever is heard in the background, be it music, your phone going off or the TV turned down. The PC then identifies it, using fingerprinting, and then shows you relevant content, whether that's adverts or search results, or a chat room on the subject". I don't know about you but this is going a bit too far for me.
And they use pigeons to help with their search results http://www.google.com/technology/pigeonrank.html
George Orwell called it Big Brother. It's real name is BigDaddy. Not quite a reality yet but getting closer all the time.
As the original article says, "Given the furore caused when AOL released searches on the internet, there might be more than a few civil liberties activists less than happy for Google to put this idea into practice."
