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 -- Karl Dubost - http://dev.opera.com/ Developer Relations & Tools, Opera Software
