Very intelligent and ultra-helpful book, written with experience and with deep understanding. I also follow the blog and I can confirm Angry's advice shines across the whole Internet. Compared with his blog posts, his book has the additional advantage of concentrating a lot of content in a very short and effective way, with no wasted words.
The only downside (for my personal tastes) is the "angry" gimmick of the author, but in the book it is toned to a moderate level, and the content is great anyways.
