Well, Jason Adams was up to the challenge and has posted his implementation at http://tunkrank.com/. Check it out! I understand that he’s still ironing out bugs and perhaps even implementing features. He’s even set up a Twitter user for the project: http://twitter.com/tunkrank.
To others considering their own implementations: please don’t be discouraged! I believe this is a ripe area for exploration, and hopefully one that lends itself to fun hackery. Perhaps even an open source project.
Still, Jason deserves the glory for getting there first. Let’s make it worth his while by stress-testing his site and suggesting ways to improve it!
