@Galzria: Doesn't that logic keep recurring backwards somewhat though? If, according to your (perfectly reasonable) logic, the penultimate vote is the scummiest, then double-bluffing mafia would be interested in avoiding it, meaning it's more likely to be a town vote. And so on and so forth.
Of course, that leaves us in the position of not being able to extra any information from voter order which obviously isn't accurate either. So take any thoughts with a pinch of salt.
Sorry, didn't mean to ignore you here:
Yes, you could get into that spiral... But at some point, looking at the players around you, you have to wonder how far a bluff might ACTUALLY go.
People suspect vote #1, as it's the least reasoned (often)
People suspect the final vote because it's the one to get the job done
People suspect everything in between as bandwagon
I would posit that perhaps, there really is nothing to be gained from vote order
when considered as it's own entity. But combined with reasons given, past stances, and stated preference for day length (By the way, what are your thoughts on allowing the day to go on, for the sole purpose of getting more posts or there?), I believe there is much to be gained from vote order.
