I waited and waited a long time before posting anything on this. Google clearly understands that they need to show search related contextual AdSense ads on our forum. However, Yahoo! is showing ads about "Ionic Air Purifier by Oreck".
I figured I would wait until the forum was a week old before saying anything. Then I waited even longer but it is still showing these ads. It is a good thing I have my ads on rotation with Google AdSense and YPN.
But I do not rotate the ads in the RSS feeds or email subscriptions. So it looks really bad.
