I have several mainstream sites with high listings in their respective DMOZ categories, and they don't pull a lot of traffic from the listings. I got lots more from basic Google text and image searches. I think there are better people to try to corrupt to get more traffic.
I even have a site that's listed in a reference within what I understand is a popular Wikipedia article (I didn't put it there). Very little traffic. There's no SE juice from it because they nofollow their external links.
