Ever walk up to a door and pull on the handle, only to discover the door is push-only? Do you really know how to operate your clock-radio? Doors may be pretty, clocks may look cool, but when we have to actually use them, the measure of their design changes.

Same with websites. A website may be pretty at first blush, but can you find what you're looking for? Can you do what you want to do? Can you even figure out what you're supposed to do?

This presentation is on functional design concepts and how they apply to websites and web apps.

If you have any suggestions for sites to include -- really good or (maybe more fun) really really bad -- please contact me.
