Greenspun has an easy-to-read writing style and a wry sense of humor. (The book has no CD ROM attached to the inside back cover but a picture of a CD ROM with the international "No" symbol overprinted. All code an more is available from Greenspun's Web sites, as you would expect from a book about Web sites.) He also emphasizes esthetic choices and subscribes to a minimalist visual style, in the book and for Web sites, that enhance reading and make downloads as fast as possible.
Your VP will understand it, and your MIS manager will be able to use it for something.
You can read the table of contents and get a feel for the book. But what is best is Greenspun's attitude.
I think his best comment is that the hard part is the design and the easy part is to "Write a couple of programs that parse the HTML forms and turn them into actual database transactions". (pg 172) And then he provides examples of doing just this.
But as I said, Greenspun has an attitude that is very refreshing.
