They should let people have more control over what ads they do and don't see.
If Google served me ads on stuff I was interested in (I'd be happy to tell them) rather than women's clothing, they I might buy it. I'm a guy - show me as many skimpily dressed women as you like, but I have no need for women's clothes! Try it once or a hundred times it you must, but maybe after the millionth non-purchase you'd think they might figure it out and use that screen real-estate to serve an ad for something that my purchase history or what they know about me indicates I might have some interest in!
Dumb as a rock.
