We all know about friction. It's the dry friction we are most familiar with but there are several types of friction. Friction was discovered by Leonardo da VInci although he didn't get credit (posthumously, of course) until the 17th century when his codices were discovered. Ever hear of the coefficient of friction? Leonardo didn't coin the phrase he merely described the ratio. While there are fun facts about friction and Leonardo, there are more serious sentiments about such a force.
Rob's article is less about history and science and more about the impact (not a pun) on human nature. Here friction is not a physical force in mechanics. Adding or reducing friction is a metaphor for slowing or increasing communication pathways, or slowing the pace of development or facilitating it. There is more in the article than this little intro, so click Friction. It's such a good read.
