Nice theory Brett but this is just wishful thinking. In my competitive area, many of the new entrants are the ugliest, lamest, least useful, out of date, socially inept websites you've ever come across. The idea that these pages are engaging customers better than the entrenched real businesses they ousted would take some believing.
On the otherhand, I can see that this is the future of Google's algo once this initial weeding out (or is that dose of pesticide) has taken effect. It's definitely the way to go, since it makes every web-user a google quality rater (instead of just webmasters, as under Page Rank).
