Because a flatiron takes so much longer, duh!
I'm happy to get back and see so many posts. And on the note of whether or not to lynch the quiet people, keep in mind that on the last game the last baddie was silent almost the entire game, even to the point of almost being modfired. So we need to pay attention not only to how often people post, but when and what they post (e.g. popping in and voting in a close vote situation, appearing and making an accusation and then vanishing, etc.)
