From: Google Thinks I'm a Middle-Aged Man. What About You?
“See, this is all we’re concerned about in this whole tracking business. It’s not even detailed enough information to distinguish a middle-aged man from a girl technology reporter. To us, your profile is just a series of random digits, nothing more. And if you don’t like it, we are making it so easy to opt out that you have no excuse not to.”
