Node.js Knockout is a 48 hour hackathon, like Rails Rumble. Follow @node_knockout for updates.
This is the website code for http://nodeknockout.com. It was written before a lot of the libraries it uses (e.g. express, Connect, even npm) were mature. So, it's pretty gross. If you want a lesson in how to get things done, but as quickly and hackily as possible, you're in the right place.
We'll likely throw all of this out by next year.
