Oops!  When I was writing the second edition of the book, I was working with an early copy of the first edition… and repeated a typo.  It’s on page 41.  Here’s a link to the replacement page:  Choose your right column articles.

The new edition of Sites That Soar! is for users of WordPress 2.5.x and 2.6, and it’s online now!
