Is Usability Really Worth Anything?

Jakob Nielsen considers the correlation between usability and profitability in this article on InternetWorld. According to Nielsen, because users will shop on a usable site rather than an unusable one, he suggests that the usable sites can charge a little more. He says, "...ultimately, success on the Internet comes from serving users; that's what people will pay for." That's nice, Jakob. Don't give them any ideas.
