Peeking Inside the Google Engineers' Toolbox
Ever since I first saw Matt Cutts, Google's head of search quality, "investigating" sites through his super-secret application (during an SES conference in NYC); calling out spammers and identifying crawl and ranking issues for curious site owners, I've wondered about the content of his tool collection.
