I have long been an advocate of usability on the web: basing design on what is easiest for the user. Far too often, we worry too much about what looks good and too little about the ease of use. We forget that without users, nothing else really matters.
I recently found a great article on usability. As I was reading it, I kept thinking “Am I doing that?” I think I will be referring back to this article for some time, as I work out the layout for this site and other projects.
