Joe Clark writes on the culture of antidesign predominate at Google:
Companies committed to a culture of antidesign (also consultants like Jakob Nielsen) may occasionally succeed in the marketplace, but they do so in spite of their antidesign, not because of it. Of course we can’t prove that; we can’t run a controlled experiment, let alone 41 of them with distinct shades of blue. It is merely one of those things a visually literate person knows. The fact that you don’t know it, or you deny it’s important, or deny it even can be known goes to show you really are better suited to programming a computer all day than dealing with actual human beings.
