Google does offer a browser plug-in that maintains your opt-out even when cookies are cleared, but it's only available for Firefox and IE. So, you're out of luck if you're running Safari or Opera - or Google's own Chrome.

Google is offering something called an Ad Preferences Manager, where you view and edit the ad categories Google has placed you in based on your past behavior. If you like, you can even tell Google to serve you ads in additional categories.

You can also opt-out of the program. But this is a cookie-based opt-out, which means you'll have to opt-out on every machine and every browser you use. It also means that if you're someone who regularly clears your cookies for privacy reasons, you'll opt yourself back in.
