Shipping mix.fiftythree.com on Node.js

My excellent colleague @gscottolson has proposed https://github.com/brooklynjs/brooklynjs.github.io/pull/95 to talk about building the front-end of mix.fiftythree.com with React.

I'd love to also talk about our focused effort shipping the back-end, built on Node — in particular, how we dug into some performance issues and made it fast. Some very interesting discoveries and lessons learned. (E.g. around event loop blocking, and how significant that is given single-threaded-ness.)

It'll also be fun to share a bit about the tools and frameworks we've built on, e.g. Streamline.js.
