Tim's User Interface Guidelines -- "The following concepts have served me well in my job as an interaction designer/visual designer. While this is a short, general list, if you understand and can articulate these concepts to others through your information design, architecture and visual design efforts, the web could be a very different place than it is today." (Comments: These guidelines were originally posted in December, 1999. That gets me thinking. How immutable are the laws of usability? Are they immutable at all? Technology changes all the time, but humans don't. At least at their core, as a group. For example, one hundred and eighty-four years ago, people still had to poop. Oh wait, nevermind, there are no laws of usability.)
