Building mix.fiftythree.com with React

The web team at FiftyThree has spent the better part of two years working on [Mix by FiftyThree](https://mix.fiftythree.com/). The web service integrates with [Paper](http://www.fiftythree.com/paper), the award-winning iPad app, and allows creators around the world to collaborate directly on their devices.

The web front-end of Mix is built on [React](https://github.com/facebook/react). We launched Mix on September 16th, so this is our first chance to speak publicly about the engineering and technology behind the service. I want to share some of the challenges and benefits of building a large-scale web app using React components.
