I purchased this book after browsing it at the bookstore and reading about all the nifty extra downloads available at the book's "companion site." Guess what? All the reviews are right - there IS NO SITE. It is now May of 2007 and the site STILL says it is "coming soon," with no explanation. The companion site (which sounded very cool in the book)was never developed and not only is there no explanation at the site - but not even here at Amazon where Matt Haughey and the other authors have the opportunity to write in the book blog - or leave comments to the reviews in answer to all those wondering about what happened. I just don't get it. The silence is deafening. No site? A disappointment, but no problem that can't be forgiven if someone just took the time to offer those of us who spent $30.00 an explanation. But even after 2 years of publication, that seems to be too much trouble. Shame.
