Rob,colleague of mine, pointed me to an article about "Evolvable Systems":
Why something as poorly designed as the Web became The Next Big Thing, and what that means for the future.
First of all this article is very interesting, but the whole site -that I did not know- is full of truth, and fun ! ( I love the one about blogs)
I invite you to bookmark http://www.shirky.com !
Thanks again Rob!
