Spoilers are a weirdly divisive issue among science fiction fans. Some of us love to know the endings to movies, books, and TV shows before we dive into them; others want to know absolutely nothing before plunging into a story. We've had a few grumpy emails from io9 readers who aren't happy with how we've displayed spoilers in posts. We're not going to stop posting spoilers, but we're willing to warn you first so you can remain pure. Now you can vote on the best way for io9 to handle spoilers.
