Via Dare comes this tidbit from Om Malik on the disparity in advertising rates between Google and MySpace:

Like all community sites that rely mostly on their users to author content, MySpace has had a very difficult time trying to secure high advertising rates. Historically, advertisers have held little trust in content that is not tightly controlled editorially and, therefore, the value they are willing to attach for ads placed next to such uncontrollable content has been very low. The result is clear… MySpace ranks higher than Google in terms of pageviews, but Google will gross $6 billion in revenues this year, while MySpace will generate about $30 million. The delta, which can be measured in orders of magnitude, is almost unbelievable. I realize the comparison is not directly apples to apples, but even so!

Like Dare said, that's stunning. If someone doesn't charge in to grab that potential revenue, I'll be astounded.
