It's a great article and definitely outlines the need for iterative design, but I don't agree that it should be a principle. More thoughts if anyone cares:
The best designs copies nature. Nature is lazy (energy-efficient) and elegant.
Example. Soap bubbles quickly settles in shapes that are most efficient.
For us humans we're not as intuitive with nature. We have many distractions and conflicting goals. It takes us more, and longer, iterations to figure out these things.
We're just not lazy-enough.
Actually, that's the beauty of shipping new design tweaks or features frequently. People are slowly introduced to changes and are eased into a new design instead of one day waking up up to a completely new design they have never seen before.
