title: Firebase Scalability Limit
body: <p>This <a href="https://groups.google.com/forum/#!topic/firebase-angular/OY7xtpoc9XA">post</a> says that FireBase will  have an issue coming when an individual node begins to have 1-10+ million children. 
  How should one handle Users in an app if we have more than 10 million? In all the examples I though Users were simply children of a single node "Users".</p>
