Yeah, it's been debunked. There are claims on there that are exaggerated. For example, I'm pretty sure it was even shown that one of the constellation configurations the author points to isn't even accurate (when he's building his case for the pagan origins of christianity). Admittedly I'm a bit embarassed to say I swalloed it up whole myself, but then it occured to me that I'd better check it out before I use it as a source. As you can guess, it's been shown to be not fully correct by credible sceptics (including sceptic magazine). I don't know about the money monger part of it, but the 9/11 conspiracy theories have never been supported very strongly either.
