On Facebook, Scholars Link Up With Data - New York Times

S. Shyam Sundar, a professor and founder of the Media Effects Research Laboratory at Penn State, has led students in several Facebook studies exploring identity. One involved the creation of mock Facebook profiles. Researchers learned that while people perceive someone who has a high number of friends as popular, attractive and self-confident, people who accumulate “too many” friends (about 800 or more) are seen as insecure. … Eszter Hargittai, a professor at Northwestern, found in a study that Hispanic students were significantly less likely to use Facebook, and much more likely to use MySpace. White, Asian and Asian-American students, the study found, were much more likely to use Facebook and significantly less likely to use MySpace.
