Mark Malkoff's Netflix Challenge

Since you pay for Netflix by the month, how low can you bring the price-per-movie down by watching as many as you can? Mark Malkoff tried to find out, by devoting a month to the experiment. I don't see how he did it, because I couldn't find anywhere near that many movies I'd care to watch. There's a list of the films he saw at My Damn Channel. (Thanks, Mark!)
