Update: How @Google Works

@MattCutts today posted to Google+ about a video he uploaded for webmasters, about how google works (something I recently wrote about and posted an older video too). If you are interested in search this is definitely a video to watch. http://www.youtube-nocookie.com/embed/KyCYyoGusqs

So what did Matt miss out? what was there you didn't expect? Let us know.
