I'd actually like to do that too but have a hard time wrapping my head around the notion of building a website with node + nosql alone. My understanding is that node is best for realtime chat-like apps.. Is your project web related might I ask?
However, that doesn't mean it isn't well suited for building a website. You'd probably want to include some add-ons for that though (eg: express).
Note that even for realtime chat-like apps you'll probably need some kind of datastore and in fact that example sounds like a great use case for nosql as a datastore.
Since you asked, my project is over here http://jobstractor.com if you want to take a look. My email is on the site so feel free to drop me a line if you have any questions. I'm planning on writing up my experience and a bit about how I've structured things so some questions might help me think through that.
