Stripped out the HTML5Boilerplate stuff -- not because it isn't awesome (it is), but because it distracted from the main point of the sample app.

In practice, you really should take a look at http://html5boilerplate.com/. It's great. But, like I said, people tended to get confused about what was necessary for game services, and what was unrelated HTML5Boilerplate elements.

Note that this might mean your game runs slightly less well in non-Chrome browsers.
