Don Normon on Edward Tufte: “His famous denunciation of the NASA slides, where he points out that critical information was buried, is not a denunciation of PowerPoint, as he claims. The point was buried because the presenters did not think it important. They were wrong, but it is always easier to find blame in hindsight than with foresight. The slides matched their understanding of the importance of the issues.”

Aside from the above, it's interesting to see that Don Norman is described as “a strong advocate of user-centered design” when the page on which his interview appears does not have a meaningful title and uses Javascript links. Guess Norman didn't stick around long enough to give the site of the publication that interviewed him a once-over.
