“Today the user experience is not just a set of widgets or a website design. As Leander Kahney explained in his book Inside Steve’s Brain, for Steve Jobs design is the function. This is increasingly true about any modern web application. Users perceive all elements of the service as the service itself. They don’t distinguish particular widgets inside Twitter or Twitterific; the vertical conversational faceroll defines Twitter. The way the service is delivered is why users like it.”
