By now, a few more readers have written in with (mostly minor) reports, and I've updated the errata page.
And also by now, a few more reviews have been posted in various places. They're all rather positive. For pointers to some of my favorites, see the reviews page.
And, a request: if you enjoy my book, please consider reviewing it in an online magazine, online bookseller's web site (Amazon or elsewhere), blog, or web site. Reviews really do make a difference in getting the word out and helping a book succeed.
