Great video but just to make sure I understand it, is there any real difference between how Angular controllers inherit $scope than functions and objects in plain old JavaScript inherit from their parents and pass down to their children (if the children request that data and don't overwrite it). A 'trickle down' affect?
Having spent some time learning about object prototypal inheritance and the scope system in Js, Angular doesn't seem to be as hard to get my head around as I first feared :)

$scopes in Angular are prototype chains just like you're thinking. The top level is $rootScope, and all $scopes in your controllers inherit from that. Then any child $scopes you define create another level of $scope inheritance, but they are plain old prototypal inheritance!

When you add the ng-app directive, you are declaring that your app starts at the tag specified, and also ends at its corresponding closing tag. So if you add the ng-app directive the the 'html' tag, your app is bootstrapped for the entire page, between the opening and closing 'html' tags.
