I actually joined about a year ago and the decision had already been made to use Rails to run our API and server-side code. We have 4 different apps; one of the major ones is already using Rails/EventMachine to power it and we've learned how to scale it. I'm not sure why Node.js wasn't seriously considered for this rewrite, but if I had to guess, it's because we didn't want to take the time to learn a new thing, we've got a legacy system that badly needs customers migrated off it, and shipping something soon is paramount. I'm sure at some later date, we'll move all our stuff to JS. It seems inevitable with the way things are currently headed.
