I know exactly what happened, they started asking people in the forums what they wanted to see in the last episode assuming that human beings, known throughout the universe for being the most fickle creatures imaginable (especially in this society), would have any idea of what they actually wanted.
More and more shows are running afoul of that problem. Giving the creators of a show direct access to instantaneous fan feedback can be absolutely disastrous if said creators can't hold on to their own vision of the show in the face of it. It's not that listening to fan feedback is a bad thing, but you can't let your audience run the show for you, they've no idea what they actually want. I'm entirely convinced, for example, that this is what happened to Heroes.
This is a problem in other media too, it's even destroyed a few otherwise promising games. One of the great things about AI War, actually, is that Chris has so successfully managed to balance the integration of player feedback and ideas without allowing that to compromise his own vision of what the game should be.
Hey, look at that, I brought the tangent back around to being on topic.
