==The speed of meme propogation=====Hi delta of percived Value make meme propogate faster=== In a theoretical model on decisions in social networks (also called innovation adaptation), it was found that as the gap between the individual ́s perception of the options is high, the adoption speed increases if the dispersion of early adopters grows.
