"The Spoilers Code"
I basically agree with this, especially because it has an exemption for journalism and internet-based resources:
Personally, I’m in the camp of people who don’t mind being spoiled one iota—I regularly spoil myself on things I’m watching thanks to Wikipedia, and I fully believe the study that came out last summer that spoilers increase our enjoyment of entertainment. But I do try to avoid being a jerk in person. And on this blog, I abide by the Vulture statute of limitations. I know we live in a world of DVRs, and DVDs, and Netflix. But there’s so much stuff I get excited to talk to y’all about. I can’t hold off on it forever.
