Statute of Limitations: Spoilers

With the release of Deathly Hallows we have a neat opportunity to discuss spoilers and the period of time that must be allowed to pass between a thing being release and information about the thing being presented.

This article, in part, addresses the issue offhandedly.

One quote from the article favors a significant chunk of time:
"I think we should have at least a few months, allow people to read and discuss and digest before blasting it from headlines," says Leaky Cauldron Web master Melissa Anelli.

Another quote, from J.K. Rowling, endorses a shorter period of time:
"You can't be too precious about this stuff. Obviously, as a writer I would prefer people to be able to sit down and read it and discover the ending through reading the whole story. But with 'Half-Blood Prince,' people dangled a sheet over a flyover (overpass) the next day — 'Snape kills Dumbledore.' Part of me does find that very funny; I can't help myself."
