Lisa Sabin-Wilson literally wrote the book on WordPress. I've read and used both editions of her "WordPress For Dummies" and pre-ordered the third edition today.
WordPress, if not the leading blogging application, is certainly a contender for the title. To use WordPress is to love it and Sabin-Wilson's book makes WordPress accessible to all.
BuddyPress is a new product, free like WordPress, but intended to allow users to create their own "social community" on their website. This book is already behind the curve in some ways because BuddyPress is very much a work in progress. Sabin-Wilson's book came out just a couple of weeks ago. During the time she wrote it and before it hit the streets, you needed to have WordPress MU (Multi-User) installed as the base for BuddyPress. As of a week or so ago, this is no longer the case: BuddyPress will now run on the single user version of WordPress. This change, in a way, means adjusting many of the instructions contained in the book, but it Is nothing a reasonably experienced person won't be able to deal with.
What does BuddyPress do for you? Well, the author explains that quickly and clearly: with BuddyPress, you can build a community with members having their own blogs, tracking of activities, discussion forums and more. Feature like this have been available in part through services like Yahoo! Groups and Ning. But now you can run them on your own server and customize them to your tastes.
That's the real power of BuddyPress - you can tweak it meet your needs and expectations.
And Lisa Sabin-Wilson shows you how.
Much of the book will seem familiar to "WordPress For Dummies" readers because, clearly, much of it was adapted from it. By the way, if you are new to WordPress, get and read "WordPress For Dummies" first. The education will serve you well as you approach BuddyPress.
Sabin-Wilson writes clearly. The only problem I foresee is that all the instructions are based on using WordPress MU (Multi-User) which may lead to confusion on some points, but I feel certain that the author will post errata to cover these differences.
BuddyPress may be overkill for most individuals - you can get many of the same features by using Ning or other web services. On the other hand, organizations and groups may readily appreciate the power of BuddyPress. Lisa Sabin-Wilson makes it easy to find out because she has essentially provided the "how to" manual on getting BuddyPress up and running with a minimum of hassle.
