Four days, three hours and 45 minutes before the spoiling of the finale of Harry Potter and the Deathly Hallows. The first spoiling will come from the East Coast, of course. Figure sometime around 9:30 pm Pacific time. Okay, 10 pm. Make it 10:30 with all the steps involved — buy the book, run outside, read last five pages, hook up laptop in wi-fi-area, write spoiler with details, post spoiler.
