The Importance of Simplicity
According to this article by Scott Berkun of Microsoft "Web sites and software often compete with each other based on the features they provide. The popular assumption is that the more features a product has, the better it will be. The truth is that features improve a product only if they are actually used by the customer. In most cases the proliferation of features in products creates more complexity than value" (1999-07-13)
