Hugo voting is open, and several voters have noticed that the voting website doesn’t include voting instructions. Since the Hugos use instant runoff voting rather than first-past-the-post, and since a vote for “no award” can make a real difference in the rankings, this is a significant omission. Fortunately Teresa Nielsen Hayden at Making Light has put together a quick guide for first-time and forgetful Hugo voters. You can learn more about the awards and how they work at the official Hugo Awards website. Don’t forget that the deadline for voting is July 31, 2012.
