Assume that I fully embrace the concept and happily start using it, letting the system profile and pigeon-hole me to its hearts content.
Periodically, I will have a burst of activity on a particular subject, for example, I'm looking for a new car. I then start getting ads for cars etc. Great, I guess it's helping.
They store your unique identifying random number, the category (cars) and a timestamp. So over time that timestamp will decay the value of that information and replace it with you interest in consumer electronics. Though I suppose the smart data miners could start targeting car insurance ads 11 months or so after you started being flagged for cars, or extended warranties 3 years after you bought if you were searching for new cars.
