Query: Ancient and Outdated

I recently purchased this book hoping to learn something useful about developing high performance and usable web systems, but it read more like a technical manual from the 1990's. I saw all 5 star reviews but didn't think that any web book dated pre-2005, wait 2006, wait 2007, wait 2008, is probably useless. Next time I'll know better to look at the publish date, and the dates of the reviews. I can't believe how infantile the Internet was just 10 years ago. The moment I saw Jakob Nielsen endorse the book in the forward, I knew it was going to be useless. Luckily I only paid $4.57 for the book. Maybe I can walk away with one useful tip.Even if it were 2002, I doubt there's anything "Quality" about anything the book covers. Seems like re-hashing a bunch of common sense stuff anyone who is in development would know.
