Hi. I'm reading "Ajax In Practice" these days. I didn't finish it yet but I just want to say: Buy this book, if not for any thing, just for chapter 2. The contents of this chapter worth every second you spend reading it, actually, I'm planning to reread it again and again. Also, I got "jQuery In Action" book, an amazing writing for an amazing library. I don't find jQuery a mystery any more. Thank you Mr. Bear, Mr, Yehuda, Mr. Dave and all other great writers of "Ajax In Practice".
