Just think if Google decided to sell the information they have on you; they recorded every search from everyone, everwhere since they started!
Just imaging you could find out if someone had a dog, guns, when they were going on vacation, what type of electronics, stereo they had, if they had an alarm, etc.
There is no more privacy, and access to imformation is a double edged sword!
I don't use Google anymore, and don't even get me started on Facebook:
