I like Nielsen. He talks common sense. His first book on Web design ('Web Usability') should be the bible of Web designers - but as as this new book shows, the same old mistakes are made time and again. The first 50 pages are great but then he analyses actual Web sites for the rest of the book - and this would be OK if they were different. But they're all pretty much the same so you don't learn much after the first few reviews. Sloppy research. But I still recommend the book. Give it to your IT guys.
