The speed of meme propogation
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<ref> [http://arxiv.org/ftp/arxiv/papers/1011/1011.3834.pdf Laciana, C. E., & Rovere, S. L. (2011). Ising-like agent-based technology diffusion model: Adoption patterns vs. seeding strategies.

===Pareto law of speed of propogation===
Meme propagate through 50% of a network in in short time, and reach 80% in longer time (in students connected through a mutual social network it takes 10 minutes to reach 50% and about 100 minutes to reach 80%)<ref>[http://research.microsoft.com/en-us/projects/ldg/a05-zhu.pdf Zhu, K., Hui, P., Chen, Y., Fu, X., & Li, W.
