This, in concept, really epitomizes an unfortunate trend towards making programming and development "easier" and "more accessible".
As I see it, this is no longer "Node.js, JSON, MongoDB, and Cloudfoundry". It certainly uses all of those technologies, but in reality, you are learning "Fire.js".
Even with a polished version, it doesn't seem like a developer would ever learn how to use the underlying technologies in an expressive, applicable manner. It just comes off as another excuse for developers to side-step learning about and getting into "the thick of it".
