I can imagine a world where advertising is good in the sense that it's always relevant, but such a world places heavier weight on ad "fit" than on the advertiser's bid for that ad inventory. For example, it's a bad user experience when you search for a product/vendor and the first result is their competitor instead because they bid more for that ad placement. Unfortunately, I don't see how "good" advertising can exist outside of small niches with the economic incentives being what they are.
