This book just tells it like it is. Steve Krug gives you some of the best experience he has as a usability expert for the bargain price of this book.
It is easy to get wrapped up in debates about how to organize a website. This book acknowledges that many of these debates are based on personal preferences rather than real-world usability data.
If you pay attention to this easy-to-read material and exercise it on your websites, you will improve your vistors' experience and opinion of your site.
Not much too add beyond what many of the other reviewers have said, except that it was a real pleasure to read such an approachable book, and get so many good ideas in such a short amount of time.Note: this isn't a book about theory. It's about what works and doesn't work in practice and that's it. Krug gets right to the heart of the matter on every point. If you're looking for detailed discussions of web design techniques and why they're good or bad, this is not the right book for that.
I've been working in the web industry for over 5 years now, and pretty much thought I had it all figured out, as far as usability is concerned.
Wow, was I wrong. Reading Krug's book opened up my eyes to several important aspects of web usability that I had overlooked. I especially found the section on user testing useful.
This is one of the best investments you can make for your career!
