you are advertising better ads? wow ... i realise that googles only money making business is ads but i would have thought that by now you know not to bring the ads to the users attention unecessarily. yes, you need to improving the way that you show ads, but use focus groups, or small studies, workshops, not telling everyone. "better ads" is the worst upcoming feature that i can imagine
