Knowing about a new service or technology won’t make people adopt it. Would you bother creating a Facebook account or learning the ins and outs of a new software tool if nobody else within your close circle was using the social platform or computer program?

Centola’s highly informative article is a must-read for anyone interested in the diffusion of innovation.
