You can see how sites rank using standard ranking methodologies based on the contents of the CommonCrawl.
It appears to be the 2012 CommonCrawl as the 2013 CommonCrawl was just released in November. They said it's Common, not Quick or Current.
Sadly, they ate a lot of 403s from some of my sites that don't appear in this index.
Overall, I think this is a good wake up call for delusional webmasters that wonder why their websites don't do better in the search engines because when your competition ranks above the 1M mark and your site is down around 39M or some such, you should be lucky they bother crawling your site at all let alone rank the stupid thing!
I'm just say'n...
