MIT (http://www.mit.edu/) ran an experiment (http://reality.media.mit.edu/) where 100 of their students were given cell-phones running custom tracking/interaction software. They then compiled all the movement and call information and were actually able to predict student behavior using data-mining. It’s easy to see that data-mining can predict human tastes in movies (http://www.netflix.com), music (http://www.apple.com/itunes/), and books (http://amazon.com) but predicting movements and other behaviors is kind of a new idea. It sort of makes you feel like an animal whose migration is being charted by a zoologist.

I'm all for new technology but stay the hell away from me with that kind of stuff. Call me a tree hugging hippie liberal (hey I am..) but I'll take my personal freedoms over anything else.
