I'm about half way through it, though I'm the one who submitted this post. I've been reading since his first Gervais Principle post and really enjoy the way he writes.

That being said Tempo is a lot lower level writing than most of the blog posts, not that that's a bad thing. The book is very interesting, though I need to make sure I am actually paying good attention to what I'm reading. If you've read through the Gervais Principle and A Brief History of the Corporation, and find yourself wanting a lot more, the book will give you a lot.
