I think it's great. Total newb, but I would like to work on skills to make this type of project. I'm curious how did you build it? What platform, if any, or languages did you use.
It's a Ruby (language) on Rails (framework) 3.2 app at it's core. I've been developing in Rails for a while, and I've really enjoyed it. The front-end uses a UI library called "Bootstrap", written by Twitter and freely distributed. You'll see a lot of projects use it because it makes getting a clean and functional UI much easier.
It's hosted on Heroku, which makes things like SSL, server scaling and database management all someone else's problem. I can't recommend them highly enough.
The book I learned Rails from was Pragprog's "Agile Programming with Rails". It was admittedly a few editions back, but their approach and structure suited me well. They also offer to sell you a PDF/eBook which really gets that instant-gratification going. It does assume you already know some HTML/CSS though, so it's not a total beginner text. There's also a ton of great resources at http://rubyonrails.org
