Spyware (Score 1)

Quote (from article): Internet search engines and helpful utilities from companies like Claria already know a lot about your shopping and browsing habits.

In other words... Spyware. Do we really want to reward companys for putting spyware on our computers and collecting information about us? You should be able to specify what type of ads you would like to see, not what spyware companys think is good for you.

Also, much of spyware data is not very accurate because of multi-user computers. This is more of a problem with single user environments, like Windows 98, because they have the same cookies for ALL users.
