I read the book just about as soon as it came out. It's really a great read, even if you aren't interested in creating a language. The author's understanding of linguistics is just amazing. I don't think you could possibly read the book and not learn something.
I haven't browsed the website in a very long time, so I'm afraid I really can't. I heard about the book from somewhere (probably HN), remembered how awesome the site was when I browsed it years ago, ordered it, and devoured it. Didn't really bother re-checking the website since I was getting the book. Sorry I can't be more help.
