I'm on the same boat. But furthermore, I'd like ads to be related to the content of the site I'm visiting. Say I'm on Quanta reading an article about black holes, how about show me an ad for a book on dark matter. Instead of an ad for a pair of shoes I searched a week ago. Contextual ads make so much more sense to me.
