He mentions inconsistencies left in to emphasize that it was a hoax, and while I'm not convinced they were as intentional as he lets on, I'm intrigued by the tone of the disclaimer. I also noticed that he only started posting reader email from after the posting of the second disclaimer.
It strikes me that whoever was behind the site forgot to account for the extent of kookism on the intarweb, and was caught off-guard by the extent to which people were taking it seriously -- especially after it made it onto the Art Bell show.
This amuses me greatly. I wonder how far out of hand it got.
