Puzzle In xkcd Book Finally Cracked
An anonymous reader writes "After a little over five months of pondering, xkcd fans have cracked a puzzle hidden inside Randall Munroe's recent book xkcd: volume 0. Here is the start of the thread on the xkcd forums; and here is the post revealing the final message (a latitude and longitude plus a date and time)."
The start of the thread, containing spoilers, isn't much use if you want to attempt the puzzle and haven't got the book. Do I need the book? If so, this is something of a non-story, isn't it?
