Abstract:

Usability is based on principles such as 'Less is more' and 'Keep it simple, stupid'. But there is more to simplicity than meets the eye. By reducing visual complexity at the cost of structural simplicity, you will give your users a hard time understanding and navigating the content of a web site.
