In a nutshell I think that the User Experience requirements gathering process is a very valuable and necessary process. However it is often a challenge in educating the client on this value and in some ways seems to annoy the client to the point where they say "Alright Already.... just show me a semi working site and I will tell you what I like and don't like. Heck I could almost do this on my own on my Myspace account!"
