Kent Beck & Tidy First?

Kent Beck, of various software implementations and processes fame, has a new book out Tidy First?. It is the first in a series on software design he is planning. This very slim book is in 3 parts. The first two have practical advice as to if, when, and how to tidy code. The recommendations are good and can be taken one at a time as needed. The third part is a giant leap away from the keyboard and into the economic and opportunity costs of tidying and software development in general. I know when I first started coding for pay no one talked about these issues and so it is great to see them succinctly presented here.
