I really don't understand why this is an app. Out of interest, what process led you to developing it as one?
We used many cutting-edge things like node.js, expressjs, mongodb, mongoose, pjax and a lot more in this project. We learned how to put these things together and how to move it to a production box.
Even if no one use it, we learned a lot. And if people really love it, another great PLUS!!
