Just saw this and it made me think of the number of reasons that permaculture spreads (seemingly) so slowly. How can we use this information to make our "brain germs" spread faster and more effectively?
Memes ( in the Dawkins/Darwinian sense ) are subject to random mutation and natural selection just as genes are. I would rather see the meme of permaculture prove itself "fittest" as opposed to fast. Game theory could be utilized to find the Evolutionary Stable Strategies. The angry memes scenario reminds me of the Hawks/Dove/Retaliator scenarios .
