Wordpress is a really awesome piece of software for managing simple websites, most notably blogs. I have been using it for several months for my clients' websites, and have been impressed by the quality of the code, the relative ease of the user interface, and the great community of designers and programmers who contribute to the knowledgebase of this free software.
If you are fairly new to the world of web publishing, this book will probably seem pretty darn sophisticated, and that's great. If you follow the instructions here, your wordpress website will probably be cooler than that of your friends, and what more can you ask for but to Pimp My Blog?
For the more experienced web developer, this book is a good guide if you've just started using Wordpress and your expectations are modest. The book doesn't even begin to cover sophisticated ins and outs, or offer any dissection of what makes wordpress such great software. So, if you already have an excellent grasp of CSS, a modest grasp of PHP, and some history of web design, this book is a great way to dive right in, but not a way to build your technical skills or deepen your understanding of Wordpress.
Enjoy using Wordpress! Since the software is completely free despite being worth hundreds of dollars per installation, the $25 that this book costs is well worth it.
