I'm enjoying it rather a lot, as he's not only a smart and thoughtful dude, but also a pretty decent writer. I've known more than one PhD who couldn't write their way out of a paper bag when it came to crafting engaging prose, and this book ain't like that.
Anyway, it's available for preorder at BezosMart. Publishers really like pre-orders. You should do that if you want to help him get the word out.
