There was an article on HN the other day about expedia increasing revenue by removing a confusing form field on their booking process. I think the lesson is that users find different things confusing / annoying than UX experts (or web designers). UX experts ramble on about 'clutter' and simplification, however, in my experience, everyday people have a high tolerance to clutter as long as its the right clutter and that clutter is easy to understand (or is a really great deal). At the end of the day, put your faith in data driven split testing, not UX zealots.
