I will admit this may have changed in the past 8? months, but the last couple experiences I had on different platforms was headache-inducing. Search (on FB docs) would turn up examples for X that just did not work. It didn't seem like the reference examples were tested when the API was updated. Blackhole/flag any examples that fail. The only thing worse than no docs is misleading docs. Another annoying event was app settings would vanish when submitting.
Edit: Okay, I went over to the developer site and it looks like things have improved more from the docs side. Progress! Can you say with certainty all the new examples work?
I'd hate to make a guarantee I couldn't stand by. Let me say this: they're all supposed to work - if you find some that are b0rk3d, please let me know and we'll fix/remove them.
