Mortal Syntax: 101 Language Choices That Will Get You Clobbered by the Grammar Snobs--Even If You're Right

This smallish book can't decide if it wants to be a style guide, vocab primer or grammar guide. Most examples are straight-forward and covered to some extent in many other sources, online and otherwise. Often, what the author describes as a "language choice," is rather an incorrect usage or spelling.
Someone actually spells out the word COULD'VE as COULD OF? That is not a choice; that is ignorance.
This is a gift for friends who have lapsed into writing (if they write at all) at a grade school or middle school level, and can find the humor in being called on it. It is certainly not of use to those "grammar snobs" mentioned in the title.
[edit May 27, 2008] I have since re-read this book in a more generous light, and have come to appreciate the writing style and humor Ms. Casagrande has included. I maintain it still suffers from a lack of specific identity, and the substance trails off toward the end as if in an attempt to make "101" at all costs, but I can no longer deny that the author is, in fact, clever, thoughtful, and imminently resourceful.
Sorry, June.
