"The insurgents have been forced to pass things by word of mouth, rather than use more modern, more effective technologies. This should help disrupt the coordination and pace of their attacks. Attacking a convoy when you've got to send the message via pony express is a hell of a lot more difficult than just calling your buddy with a mortar up the road."

Tell me something, if you lived in a dense, urban area your entire life and it was suddenly under occupation - would you really find it all that difficult to network with your associates in a face to face manner? Aside from the chance that you'll get hit by a random explosion directed towards American forces, I don't think you'd find much trouble. What if you had half of your family ziptied and carried off to interrogation for no apparent reason the month prior? Might motivate you a little bit to overcome your technical dependence, of which I'm sure the Iraqis had little to begin with. Think outside the box, buddy - the article already shattered it.
