Jeff's presentation is based on material covered in his book, Web Bloopers: 60 Common Web Design Mistakes and How to Avoid Them, which is available at Amazon.com. By conscious decision, Jeff omitted some of the less interesting subsections and focused on the more intriguing ones. His presentation began with the most fundamental problems, such as flaws in the content, and flaws in the back-end architecture. Gradually, Jeff transitioned to more superficial problems. It was strangely interesting to experience a presentation that was both funny yet also very sobering and informative.
