ASP.NET AJAX: Alessandro's book is out
Alessandro Gallo's (aka Garbin) book ASP.NET AJAX in Action is out and you can order it from here. I've met Alessandro on MSN during the early days of ATLAS and we've had several cool discussions about the platform. I'm sure he has done a fine job with this book. So, if you're looking for a good english book on AJAX, then go ahead and check this one here (btw, if you prefer to read in portuguese, then don't forget that i've also writen a book for FCA - sorry for the shameless publicity, but i just couldn't resist :) ).
