Don't even bother with this book unless you've also read Jakob Nielsen's "Designing Web Usability : The Practice of Simplicity" -- his vastly superior work. It's not that the content of "Homepage Usability" is wrong. It's actually insightful analysis... repeated 50 times. The redundancy is the problem. I like Nielsen's work, and it's important to me because I manage a popular website. But this book feels like it was something written as a regular column for a monthly magazine. The redundancy is has a nice preaching-to-the-choir effect if it's a once-a-month reminder; it's mind-numbing if you try to ready 50 of them in a row.
