I am a programmer. I don't write Java or C# or Perl or any server side code. I am the guy that works on the interface side of web sites doing very complicated XML and XSL. This is the first book on programming that understands my role on web projects and that pure software development methodologies don't take my needs into account.
The clear online of roles and how team members can work together to create powerful websites given by this book is great. I also really liked the chapters describing how to use XML and XSL to separate content from presentation. It has given the sites I work on far more fluid structures. Hats off to Wallace, Aufgang and Raggett.
