I tried to use the FB API, expecting a mature API with bindings and libraries all over the place, lots of simplifying modules etc. I was left with the impression that I wasn't really allowed to use it all, because I wasn't writing an "App" (or perhaps because it wasn't running on a "Device"). Totally confusing experience, where – even if I'm not particularly accustomed to walled garden situations – the terminology and workflow just doesn't seem to match expectations at all.
