Summary: useful reference
★★★☆☆ This book is about using free tools on the web to become fairly adept at putting together a web site without going through the rigors of actually learning how it’s done. It would be useful as a reference, but it would not make a good book to teach from. It seems a bit unfocused for teaching. On one page it will include complex bits of Ajax and on another page it will tell the reader how to behave as a member of a mailing list.
If you are interested in nothing more than having a WordPress blog with some very nice features, this book is perfect for you. I found it best when it explained Ajax, Libraries, tweaking PHP, and some of the material in the Yahoo! Developer Network. Assuming, of course, that your blog content was worthwhile, you could use this book to establish a very successful presence on the web as a blogger without reading anything else.
