Hey Brent!
Thanks for the kind words.
Atomic Design is out now actually! You can get it in both paperback and ebook formats over at the shop (http://shop.bradfrost.com/) or continue reading it online here: http://atomicdesign.bradfrost.com/
I had a really great experience writing the whole book in the open, and I'm glad it gave people the chance to read the text as it came out. I love the ability to send people links to specific sections.
