My first book is finally starting to show up on the Internet!
http://www.amazon.com/ASP-NET-3-5-Social-Networking-Enterprise-ready/dp/1847194788/ref=sr_1_1?ie=UTF8&s=books&qid=1225408005&sr=8-1

This book explores the creation of a social networking site or community site from the ASP.NET/C# developers point of view. The application that is built follows an enterprise approach to building a web site and utilizes concepts such as domain driven design, repository pattern, structure map, inversion of control, test driven development, model view presenter, and ajax. It also explores the non-technical side of a community which covers topics such as tag clouds, blogs, forums, profile and account management, etc.
