The .NET Zone just published an interview with Kry and me.  Check it out:

.NET Fireside Chats - Brad Abrams and Krzysztof Cwalinaimage

You can learn some interesting stuff about what lead to writing the first edition of the book, what a 'Framework' is and what the hardest framework design problems are. 

I'd love to hear your feedback and thoughts

Oh, and they published a sample section of the book for free in PDF format.  This is from Chapter 9 and covers LINQ guidelines.
