// it may at some times be empty, it may have some stuff later -- you're just binding to it. No promises for you to worry about
// you could do the same thing with the API call currently in your controller, and then break out code that consumes that data into other components.
// to make this even fancier, you could add Ember.run.debounce to avoid race conditions
