Freshness Algorithm

OK, so I never figured I'd be teaching algorithms and current events. Today the New York Times ran an article about Google's new search algorithm: http://bits.blogs.nytimes.com/2011/11/03/google-changes-search-algorithm-trying-to-make-results-more-timely/?hp

This should make a great start for a discussion board posting for the CS Principles class.
