Love this thread. I'd like to make a recommendation that the next time Brett updates the sections here at WW, that he considers a section just for mega sites.
We mega site webmasters have unique challenges, and it gets tiring having people who don't understand these challenges make outlandish accusations because they are used to SEO'ing their little 4 page websites. Since few of us want to display our sites in our profiles, it's hard to identify who is working with a large site and who isn't.
To me, this is the biggest weakness of WW.
