I apologize but I can't stand seeing a billion articles on this topic. Can anyone tell me why they care? It's not like Google is selling information to identity thieves. Google can piece a life together? Cool! It's so big it wont know what to do with my life story; however, I'd love to see what it is (through my google searches) so far.
