The Worst
Thanks to Charles Waud of Waudware for his nomination of rogerart.com. This is an artist's site with an anarchist style, so I'm giving it lots of latitude. However, he is trying to sell his art too, so the rules still apply. There are many obstacles to getting the artist's message across. Here are a few:

* run-on pages - The home page goes on forever ... and ever ... and ever! This is an extreme case, but remember that viewers inevitably give up on pages that require them to scroll down more than one or two screens.
* poor navigation - So, where do you go once you get there? Many of the images are links but go nowhere. Much of the text is underlined for emphasis. Is it a link or not? Who knows! If there are other links, you probably can't find them. Which leads me to
* text styles - or lack of them cause confusion. In this site the use of multiple colours, sizes and styles - even within a single sentence - is reflective of his anarchistic style, but results in a page that is so overwhelming it is never read. As far as I'm concerned, no readers, no message. Remember the K.I.S.S. principle.
