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.
feel free to approach:)
