Very easy to read but full of useful advice. Every web site owner and web designer needs to read this book. The recommendations could easily add thousands to your bottom line if you're selling on line. I particularly liked the "fixed" versions of home pages with the description of the "problem areas". All the other points covered were very clearly explained and easy to take on board. Particularly useful sections covering home page design and testing sites for usability. I bought four books about usability recently and this is easily the best.
