Another example of how negative publicity can have a big learning effect (if understood). From a new entry @ slashdot about Multi-links, I surfed to WebsitesThatSuck. The authors are committed to show the worst designs that live on the web.
With respect to Software Design, my dialy work, a similar initiative has been around for a few years. In response to the popular Design Patterns book written by the Gang of Four, others introduced the Anti-Patterns as a means to teach designers about the dont’s in the design of systems using Object Technology. You can contribute to them using the Anti-Patterns Wiki.
