Right. There are all kinds of great services that could be built on top of other peoples' web sites, but most sites want to own the relationship with their customer directly. And most of the great ideas for mashup services are predicated on the idea that the mashup will get most of the revenue, which is not going to fly with the underlying value providers. In an ad-supported web world, those who own the eyeballs call the shots.
It's a tricky problem. I just have to believe there's a way we can make the world work without ads at all. They're just gross. But I have no idea how that could happen.
