Open source methodoligy has been adopted by many people in wide range of fields. It was mostly popular with software development (Linux, Audacity and what not). It has more recently been adopted by makers of hardware, take for example Local Motors who developed an entire car using this open source philisophy. And partakers in open source architecture projects have been kicking face helping those in need all around the world.
I'm wondering if a small city or town, could perhaps be designed by a large global group of experienced people and it's design be moderated by experts. Think of all the altruistic services this city could provide for us. My question to you is, do you think this could be a new branch or direction city planning takes?
