Netflix Prize Leaderboard Landscape

Netflix recently extended the leaderboard to display more than the top 40 contenders. I submitted an entry last week using a crude algorithm just to try out the submission process, and it looks like that put me in 270th place:

It looks like there are around 250 people in the running who have submitted in the last 40 days:

You're just mad because you know I'm right:
