Dan Roam has won SlideShare's 2009 Best Presentation Contest with a napkin-style presentation about the U.S. healthcare reform plans. A good choice I think. The bar is rising. The idea of how to make beautiful presentations using large and stunning images has spread. Next challenge: how to use visual communication to get incredibly complex subject matters across. Congratulations Dan. A related post: my review of Dan Roam's book: The Back of the Napkin.
