Before, you had to explicitly call every subscriber with the initial state. Now, you can call myObservable.initialize() to do that.
Beyond DRY, this is helpful to encapsulate who the subscribers are. For example, for the selectedCity observable, we'll have subscribers from several files and we don't want to have to couple them all together.
