You don't need to know google, it is google who needs to know you. And by Zeus and company they do know you well. Oh, they know you, they know every-damn-thing about you. And how do you measure them, describe who they are. Sand is traitorous bastard. Remember, how happy you were playing on the beach building sand castles, digging for imaginary gold? But little did you know that when you grow up that sand, that same sand will run the planet and enslave humanity by transfroming itself into thousands, millions, billions computer chips that would decide our fate!
