This. The fb platform is fine for small start-ups who don't have any expectation of SLAs, or huge partners like Zynga who drive their profits or traffic. But I'm at a $600m ecommerce company and we've found their platform to be a disaster. APIs don't work, questions are answered months later by interns who know next to nothing. I know they spend a ton of money/time on it, but it's seems mostly internal facing at the moment.
