Our "Beginning Ajax with ASP.NET" book is now for sale on Amazon. Please buy 3 or 4 for the ones you love.
Appologies for the spamminess of my continual postings on the subject. Writing a book is very painful for me, so getting one finished is a major accomplishment for me. I am really happy to have worked with Paul Glavich, Scott Cate, Craig Shoemaker, Steve Smith, and the folks at Wiley on getting this accomplished.
