Excellent article. I think the usability and user experience are two different concepts but interdependent. When a web site is not very usable, users have more difficulty navigating between its content and find what they need. Usability is often a cause of poor user satisfaction (negative user experience) and in the long run the bad user experience reflects negatively on organic ranking of the website.
