Understanding Monads

$40 seems really expensive for a short book like this. I'd love to read a few objective reviews to see if it's worth the price.

For $10 I'd buy without thinking. For $20 I'd probably buy with an Amazon type consensus. But for $40 I'd need a few trusted reviews before a blind purchase from a self publish.

Not that there's anything wrong with self publishing ... just that there's no judge of content or quality as there isn't a "style" for the publisher.

That's a fair comment. I didn't buy the book completely blind; I read a tutorial Brisbin wrote on his blog on building a simple web app with Yesod. I thought he wrote clearly and concisely, and he didn't gloss over parts that would otherwise be a total roadblock for me. As I mentioned in the article, I don't know the guy, so I can't speak on his behalf. But, maybe write to him and see if he can cut you a deal?

In any case, I'm not made of money but given the choice again I wouldn't hesitate to pay the money to gain that much knowledge.
