"Thoughts on Simplicity" is the blog of John Maeda, a professor at the MIT Media Lab. I've been reading it for a couple of months and I always take away intriguing ideas, especially about how to strive for simplicity and elegant design in our cluttered and complex world.
Maeda periodically posts his Laws of Simplicity and he says he'll stop the blog when he'll reach the sixteenth. He's now up to ten. Here is Maeda's Tenth Law of Simplicity:
Less breeds less; more breeds more.
Equilibrium is found at many
points between less and more,
but never nearest the extrema.
