We can view the poll results as the votes are coming in; but I'm not sure if that's wise.
At the moment I'm inclined to hold my vote back, and use it as a tie-breaker should the need arise - but this doesn't feel in the spirit of the thing. If I couldn't see how the poll was going, I couldn't use my vote like that.
I'm wondering if it would be better to wait till after the poll closed to see who voted for what.
