Jakob Nielsen: "Web design is easy: If you are thinking about how to design a certain page element, all you have to do is to look at the twenty most-visited sites on the Internet and see how they do it...If 90% or more of the big sites do things in a single way, then this is the de-facto standard and you have to comply." Brilliant! I guess we've reached the end of the evolutionary chain for web design and can stop thinking about now. Phew, what a relief!
