Knowledge Metaphor

In the Elluminate session tonight Alec Couros suggested that his personal metaphor to knowledge that was: Knowledge is more like a river than a reservoir. I like that a lot, although as an aside, I thought to myself that knowledge is like a virus, you cough out an idea, and if someone likes it, it latches on to their system and mutates. As they think it changes… and spreads to a new host.
