Please excuse me pimping my own site, but if you use PHP & MySQL - this will generate a basic working app that uses backbone.js extensively. As an example backbone app, I think it may need a few improvements to go along with the latest release as far as view binding goes. But, I feel like I plowed my way through a few common web app needs that aren't so obvious with backbone collections (sorting, pagination, filtering, etc)
