This is a great book for the insights it provides, but in my opinion, is flawed from an analytical perspective because the author writes from a painfully biased point of view.
This is a pretty solid book. It was recommended to me by a lot of people that I respect so I figured I had to read it. As a bonus, it's quite short. As a minus, it probably could be a lot shorter! Which is ironic since Krug prides himself on having eliminated all needless words.
Regardless, it was great. Especially the chapter about guerrilla usability testing has inspired me to do more of that...
