This is not an affiliate link (someone complained incorrectly about this on another post from this blog - http://news.ycombinator.com/item?id=164120). He just read the book and liked it.

Other bigger bloggers (Coding Horror and Raganwald are two big examples) DO use Amazon affiliate links, all the time. And you know what? 90% of books I've read in the last couple years are books I knew about because someone wrote about it on their blog.

If he talked about a book and didn't link to it, someone would complain about him being lazy. So if it's courteous to link, why not throw in an affiliate link? It doesn't change anything for the reader.
