You're right. I shouldn't have implied anything about the book based on this blog post. That's unreasonable. I have things I dislike about this post, but that doesn't imply anything about your book.
I should've been clearer when I first wrote my post that there's no major content in your post that I disagree with. There are a lot of things to learn before you can write actual applications in Haskell (I've been at it for awhile, and am just really getting to understand Monad Transformers). But I do think that paragraph is a bad way to put the point. It reminds me of when a student two years older than me tried to intimidate me by asking if I knew what a RECIPROCAL was.
I also think that the $BOZOLANG comment is a bad idea. Haskell has a stereotype that it's users look down on everyone else. You may think it's a nice little joke, but I'm not sure if it will translate to people who already worry about whether they're smart enough for Haskell.
