Cool project. Why can't we both collaborate on the same project instead and make it awesome? You seem to also be using CoffeeScript, eco, express and marked.
I have a few ideas about "Documentation as a Service", unfortunately I don't have enough time to devote to this project so it's kind of stagnating right now. Would appreciate your help.
So what made you create that?
I thought of making a github webhook to automatically generate gh-pages using it but moved on another project in the meantime.
I like your idea of documentation as a service and I think you have something great with DocumentUp. We can definitively see if we can do something together. I'm deep in another project for the next two weeks (at least) but we can chat on gtalk (maxime.bouroumeau@gmail.com - I'm in GMT+1) if you want, to see what we could do in the future.
