Negative Positive
Title: Virtually useless.
Review: The problem with a 'common sense' approach to usability is twofold:1)The design suggestions are solely the author's subjective opinions and have little empirical data to back them up.2)The suggestions that are well established enough to indeed be 'common sense' are common knowledge as well. It's not really news to anyone that a Web page should be visually simple, rather than visually complex.In short, if you have any background in the field at all, you'll mistrust many of the guidelines and already know the rest.
