Information overload?

As many of you know, Edward Tufte is a leading expert on visual presentation of information. I attended his one-day course last week. A couple of highlights:

"There is no such thing as information overload, just bad design."

"Clutter is not an attribute of information, it is an illness of design."

"To simplify, add detail."

"Pitching out corrupts within."

Thoughts on those comments, or any other thoughts on Tufte?
