I chose a fairly experimental stack for this application: express, mongodb (via mongoose), jade for the templates, and coffee-script.
I was able to extract and release the Recaptcha integration code under the MIT license:

I am not looking to monetize this website, as it was just a side-project for educational purposes. However, I would love to discuss the successes and challenges I faced using this stack, if anyone is interested. Overall, I found the experience quite enjoyable. Feature suggestions are also welcome. I hope someone gets some enjoyment out of it.
