In this video Matt Cutts takes a different approach to his videos and discusses the website called How Search Works.  In order to check out the site for yourself, you can follow the link below the video.

The site is really all about the advancements in crawling, algorithms and how spam is fought.  Matt goes through the site and shows you things you may not have seen before, assuming that you’ve seen the site before.
