Here is Don Norman’s website, Human-Centered Website Design ::: http://www.jnd.org and also quote taken from there,
“All factors must be in balance. Usability and functionality should not overwhelm the user, but then neither should beauty and cleverness in graphics destroy usability and functionality. Things must be in balance, and in today’s world of limited bandwidth and slow responses times, functionality requires lean, simple sites.”
He brings up a heap of interesting points, and his Personal Information, Philosophy, and Publications section is worth reading ::: http://www.jnd.org/PersonalInfo.html#InvisibleComputerStartingPoint.
