I also dug up a (possibly deleted?) snippet from Google's cache of the My Irrationalities blog. This mentioned translations for France, Germany, Italy, Spain, Portugal, Israel, and Poland: and Warner Bros optioning the film rights, with Akiva Goldman's Weed Road to produce. It sounds like it's all getting up a head of steam, let's hope the book delivers the goods.
You know, I'd really like to write The Source screenplay: that would be a lot of fun. Any offers, Mr Goldman? ;-)
