At least in our case we can rule server speed out.
We have 4 top end servers each handling a different piece, one for images, one for html etc. Best backbone in the world, best DNS, topend security, site is faster then 96% of sites on the web.
I can tell you one thing for sure Tedster, getting more PR doesnt help. Our site went from a 6 to a 8 over the last few years but no change. Deep links, root links by the droves from the biggest sites on the web. No change. Heck sites are using our site in their ads now as "featured on site.com".
I have tried getting links, getting trust, unique content increased, boilerplate decreased, social, higher update frequency, more content, html optimization, seo up, seo down, changing ip's, changing servers, changing whois, decreasing bounce rate to insanely low levels and finding the answer in animal entrails. So far im still in the dark.
