Isn't Chris Nolan the guy who directed Batman?

I enjoyed Chris Nolan's presentation on Web searches. I knew most of what he covered, but there were a few interesting tips and tidbits here and there that were relatively new to me. For example, though it seems obvious now, I wouldn't have thought to judge the scholarly quality of a text on the internet by the amount of advertising sharing space with it. I also learned how to limit a search on Google without utilizing the Advanced Search button, which may come in handy. Probably the most helpful thing I learned was about new search engines like the librarian one. 

On a slightly different note, some of the pages I found doing the basic Google search on polar bears led me to several environmental groups that I am now looking at for summer internships, so bonus there! Thanks, Mr. Nolan!
