The difference between an interface designer and a user is:
1. The designer knows many opinions (and due to being exposed to an avalanche of user feedback over the years you really see interfaces in a panopticum). But you never get enough. It's like a drug.
2. The user only knows his opinion. Every user opinion is important--to the designer.
Tufte is just an intelligent eloquent user. His interface design competence is as weak as his photography.
Without working in the field you don't get this perspective on interfaces. Tufte has an intelligent riff, but it's always the same professoral top-down "it-has-to-be-so-and-so", and sometimes he's just plain subjectively irrelevant.
