Sometimes learning how to do something well means you need to learn how it's done poorly. Pay attention to things that "don't work" to your eye and avoid repeating those mistakes when you design.

As the author notes, "If you decide to follow these you may not achieve Internet success, but these tips will surely help you start out on the right foot."
