Fast Design Process
UIE has an interesting article by Joshua Porter about The Freedom of Fast Iterations (via Matt), which details the benefits to a fast and continual design and redesign process, especially for web design (he singles out Netflix). It's an interesting idea, small improvements rather than giant leaps forward with full releases. I certainly prefer that as a user, I like to see neat little touches, although sweeping changes do have a wow factor. As Porter suggests, it does mean you build it up far less, it's a much shorter feedback loop and you can use the live services to get real testing and opinions (surveys are always a variant of the truth, I always find I adjust my answers slightly rather than comment naturally).
