This article dovetails nicely with our discussion yesterday afternoon about the benefits/pitfalls of a/b testing. One of the reasons we fail at designing for our customers or are surprised when customers aren't acting the way we think they should is that they haven't mastered the web like we have. Anyway, read the article, and then try and answer this question for me: "How do we unlearn our mastery of the web in order to design for non-masters of the web?"
