The Death of Domain Parking?

An anonymous reader found an article about the former CEO of MySpace moving into the domain parking biz. He says "I thought, it can't be that easy. So I talked to some domainers, and they said, 'We own 300,000 domains, we make $20 million a year, we have just four employees and some servers in the Caymans.'" The idea behind the business doesn't really seem any better to me than just having a parked name with a banner ad. At least, not for the internet as a whole.
