[EM] Hay voting bust, busted

[Jobst Heitzig]

Dear Peter!

Sorry to insist, but could you please show that given your new formula 
it is indeed optimal to vote the true utilities?
For this you would have to differentiate the expected utility by each 
expressed rating and show that all these derivatives vanish when the 
ratings equal the true utilities.
I have the strong impression that, because of the normalizing constant c 
which also depends on all expressed ratings, these derivatives are, 
however, far from being zero,
meaning that the expected utility is in fact maximized by some set of 
ratings different from the true utilities!

Yours, Jobst
