Re: If tracking and targetted advertising is so wonderful,
It is not.
I've bought a car 1.5 years ago, had to provide an e-mail address and soon afterward got several messages from the dealer offering me a brand new car. I've complained and they mumbled something about "being automatic" and "from the marketing branch of the dealership".
I've also bought a new fridge online. Guess which type of advertisements from the seller I am getting? Fridges. Because if I got one I must love them and could buy another. If they were really smart they would advertise beer ("Do your new fridge feels empty inside? Fill it with beer!")
