“Not only will Google now target ads at you based on your interest, but it will also let you target yourself. Anyone can go to Google’s Ad Preferences Manager and see exactly how Google is categorizing their interests. Now, here’s the really smart part: Google lets you add or remove any interest. In effect, it is inviting you to declare what kind of ads you want to see. You can also opt out of the program completely.”– TechCrunch

It took me less than 3 minutes to update my interests for Google. And I’m sure I’ll go back from time to time to tweak them.
