---- Is the OPT OUT button not working in adsense Interest Based options?

In other words, ads are available based on (1) User Interest Categories (new) and (2) Ads based on user interactions with an advertiser (same as before).
I believe Farmboy is correct. I've seen the "ads based on user interactions with an advertiser" behavior for over two years now. Google is now adding a similar feature that targets the ads by category of all sites a person visits. The only thing that will change is the sample set used for targeting the ads. It will be increasing from Google's advertisers to all sites in Google's index.
