How long should I set the duration of a SquareOff?

Setting the lifespan of a SquareOff depends on the question. If the question will continue to stay relevant for a long period of time, leave it open longer to collect as many votes and comments as possible. If the question is more timely, asking about a current or upcoming event, make the duration much shorter — when you would like to share a winner of the SquareOff.
