Peter Senge has a concept that he calls the Learning Organization. Some organizations (especially highly successful ones) learn quickly and learn well. Other organizations don't learn as well, and gradually fall behind the curve.
Just as the speed of light slows down in denser media, the Speed of Enlightenment of a Learning Organization similarly slows down with the density of the organization.
It's not hard to measure the speed of light in different media. The more refractory the media, the slower it goes. Every medium has its characteristic index of refraction which can be readily measured.
My interest in participating in Wikimedia Foundation projects like Wikinews depends on what I am able to measure of the site's Index of Refraction and the corresponding Speed of Enlightenment, in the sense of Peter Senge's concept of the Fifth Discipline as applied to the Fourth Estate.
At the present time, the status of the Code of Ethics at Wikinews leaves something to be desired.
