Are real life political election votes made public or kept anonymous?
If anything, I think keeping it anonymous would encourage more people to take responsibility and vote, which is what we want? Isn't it?
I see no advantage in making votes public, apart from satisfying the candidates' desire to be nosey.
Who voted for whom is officially documented. On MTF, if the poll is anonymous there's no way for anyone to know that, even opening up the possibility of double accounts voting.
And no, we don't want many people to vote for the sake of it, we want people to vote consciously. Getting their vote 'seen' by everyone will only further encourage them to not just vote for the sake of it.
