"Researchers at MIT and the Korea Advanced Institute of Science and Technology, modeling the diffusion of social contagion by studying the spread of Twitter from 2006 to 2009, have found that “the site’s growth in the United States relied primarily on media attention and traditional social networks based on geographic proximity and socioeconomic similarity. In other words, at least during those early years, birds of a feather flocked — and tweeted — together.”"
