Yup and each time we create a mechanism to block, the ads 
industry will decipher another hole for tracking users. 
It is a tough issue a bit like spam. On one side a powerful 
distributed industry which really wants to track users 
across sites; on the other side not enough people with a 
will (or conscience) to not be tracked. 

Interesting experiment of the day.
Start a clean profile of your browser 
(for example with Opera, you can do on the command line
   /Applications/Opera.app/Contents/MacOS/Opera -ps foo&
)

Then go to http://www.google.com/ads/preferences/view
Use the browser for one day, as you would normally do.
Then go again to http://www.google.com/ads/preferences/view
And it will shows how you have been categorized after one day 
of browsing on the Web and this only for DoubleClick
