It's a very useful book on Web usability. See reviews
here in Amazon.
Cut&Paste of a user review:
"Some of the key things that are pointed out in this book are:
1. Don't make me think: Basically the web user does not want to venture into a site that requires them to figure it out. It should be self-evident. How do we use web pages:
a. We don't read pages, we scan them
b. We don't make optimal choices, we satisfice
c. We don't figure out, how things work, we muddle through
2. It doesn't matter how many times I click as long as each click is a mindless unambiguous choice
3. Get rid of half the words on each page, then get rid of half of what's left."
