( Second Nominating RoundCollapse )
This "Double Nomination" voting system means that the members vote for things, not against them as the 3SV system does. It also removes the need for a complex quorum calculation to prevent griefers from gaming the second round. As long as the griefers continue to be only about 20% of the electorate, it seems unlikely to me that they can dominate the field at this point. If they somehow grow to an actual majority, then they win, and they deserve to do so. The Hugo Awards are not actually about minority representation, despite what some people have falsely claimed. They are designed to reflect the wishes of a majority of the members who participate.
Again, I didn't come up with this. I take no credit for it. But if someone wants to propose it to the WSFS Business Meeting, I will help you draft it into the correct technical form if you want me to do so.
ETA, May 5: There is a suggestion from David Goldfarb on Making Light that instead of "vote for 5," this would could use approval voting, in which you could vote affirmatively for any or all of the semi-finalists. (And presumably also for your one write-in.) The five that got the most votes (not marking a candidate is the same as voting No) would go onto the shortlist. This idea has merit as well, I think.
