The fact that the boilerplate app includes working examples of using the various Facebook APIs is the icing on the cake, as far as I'm concerned. I wrote a couple of apps back in the relatively early days of the API, and I remember being very frustrated by the state of the documentation and the lack of useful examples[1], and something like this would have saved me an absurd amount of time.

1: It's been a few years since I last had to do this, so the situation might have improved since then.
