This seems a little different.
I realize I was stating the obvious....The government has for a very long time tracked folks, as have commercial trackers. If you have a social security number or driver;s license or bank account....if you pay your taxes....So many things have been tracked and logged and recorded. The books you check out of the library (or used to), the magazines you subscribe to....all of this data about you exists in someone’s file somewhere.
Maybe I am just cynical because my work has always required me to have a clearance so I have always figured lots of folks know more about me than I may even know about myself.
