Would be interesting to see if traffic goes up after this and is elastic. Marissa Mayer had a talk at some conference in 2009 where she explained her early tests on number of search results on Google - 10, 20, 25, 30 - but in the end it was just about the speed associated with loading the pages that accounted for the number of pageviews and visitors.
