The Nebula recommendations have been updated. There’s still only 4 qualified short stories. Many have been nominated, but few people can agree on the best ones. Many short stories have 6-7 recommendations.
If you are reading short stories now, and are an Active SFWA member, I strongly recommend “Holiday” by M. Rickert. This story had 1 recommendation in November, and in the last month it’s leaped to 6. It’s within striking distance of qualifying for this year’s ballot. And it’s a fine story. Haunting and disturbing and surreal all at once.
It’s available from the Nebulas site for SFWA members. I wish I could link to it here for the non-SFWA readers, but it’s not available online, unfortunately.
