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.

I bought the very first edition, just to be disappointed. There's nothing in the book as good as the Gervais principle. The blog is superior. The book is a coffee-table theory of of everything, (or everything about the mind). A bit like what Wolffram did, but poorer. He's well read, but still manages to cite things wrong, partially, or not at all. It feels like Gladwell, with more ambition, and less respect for the audience.

I was a little disappointed by the abstract nature of some of the later chapters. I bought the book the same week that I stumbled on his blog, but after having read the book, I had to go and deep dive into his blog archives and only then I could connect the dots. I would also recommend reading "Impro" in parallel.
