Here's the data one would need to underline the demographic differences between Facebook and Myspace users. (We were not satisfied by the methodology of Danah Boyd's "study" even if the initial presumption was accurate.) Mark Zuckerberg's social network, as one would expect from a site which began as an online facebook for Ivy League universities, has significantly more users with household incomes over $75,000 a year. These numbers are from Comscore and understate the income divide between the two social networks. Low-rent Myspace has more middle-aged users, who lift up its household income average. Anyone out there have time to control for age?
