It baffles me why there are no large competing social gaming web platforms. Google, Zynga, EA (playfish) could easily start one. It's a guaranteed success: people love games to be social. Facebook developers are so disgruntled with the FB platform that they 'd flock in hordes to convert their games.
On top of that, facebook enforces FB credits from July, and banned adsense advertising in apps. We are not going to pay 30% of our revenue to facebook for such a crappy platform. We moved our apps to an external website.
