Ads aren't really the biggest problems to me, 3rd party cookies are. But try blocking all 3rd party cookies, and watch the problems that can pop up. Banking, shopping carts, etc. all use them, and they do track your clicks.

Google api's are the worst. If you use Firefox or Chrome, install Lightbeam/Collusion and check out who's tracking you. In 2 days, I've been tracked by some Google 3rd party cookie 32 times. They know what IP you log in from, what time you view sites, and where you go in those sights. Not tinfoil hat stuff, but there is a reason Google's makes billions from selling user data.
