I think that it is necessary to say that all of the sucess that a website could ever get is through happy users. The only way you can know about a user's happiness is through usability testing. There is nothing wrong with testing, think of it as a form of constructive criticism that all of us must endure. Krug describes how usability tests are an "iterative process", like a revision of a manuscript. However, I think that we have a luxary that professional web desigeners do not have. We have the ability to make a coalition of testing forces through the sake of education. When out in the real world, these tests churn out a lot of dollars, even at the discounted price of $300 will cause problems for us. That is how important opinion is to the web. Without it, the would not be a clear standard when it comes to websites.
