Overall a I think this chapter will help people communicate design in abetter way. Nice analogy to interior designers mood boards to Style Tiles.

"The term “style guide” is used to communicate the design standards in place for the site being developed." Should be: A “style guide” is used to communicate the design standards in place for the site being developed. "The term" leads on to think you'll be defining what a style guide is not what it does.

I hope more clients will become comfortable with this approach to designing web sites.
