On his blog, Kean Richmond posted a review of Web Form Design:

"Personally I could not recommend this book enough, although I have yet to put any of the ideas I’ve learnt to practical use I will soon be redesigning and rebuilding an ecommerce site. In the book it talks a little about how effective even the smallest changes to a web form can be to the completion figures of that form, so with that in mind I fully expect to be able to provide our client with an updated site that will much improve the user experience and also their profits."

Thanks Kean!
