It's not well known, but https://circleci.com is a one-page JS app that seems to be very similar to the book. The datasource is slightly different (we use Knockout, and so follow their pattern, with simple jquery for "saving" and loading), but otherwise it's surprisingly similar.
I use knockout.js too and I had a look at your code: although you seem to follow a lot of best practices, I noticed your code is not minified. Any reason why?
Ah, yes. We use a dieter [1] for our asset pipeline, and it supports minification using Google closure compiler. Unfortunately, this breaks Twitter Bootstrap.
I did some measurement and I think we can save 19% through minification using uglify (once you included gzipping). That means its not currently worth the few hours of making it work and verifying that it doesn't break anything (versus other ways we can spend our time). Probably.
