I think the only advantage of having a decent PR is that it becomes a strong selling point for your site. For some reason people do believe it has some kind of importance, so selling advertising on a site with PR5 would be a piece of cake. Or, consider this situation...
A) Bob is selling his fishing site. He says that the site receives 2000 visitors a day and has traffic stats to prove it. The site is a PR2.
B) Fred is also selling his fishing site. He also says that the site receives 2000 visitors a day and has traffic stats to prove it. The site is a PR5.
What site is likely to sell for the most money?
