But if you want spoilers, dive right in to the xkcd forum thread!
This happened back on March 10th, but the breadpig just got around to putting this blog together. For what it's worth, davean, the not-Randall-half of xkcd was alerted by this very porcine hero. But if blog entry is news to you, you obviously have better things to do than keep up with solving geeky book puzzles. Your loss.
The news scored a lot of attention on Slashdot and a Wired story. We don't want to ruin the surprise if you're keen on picking up a copy to try decrypting yourself, but you may want to check the spoilers as July approaches if you haven't solved it yet...
