Hare dubs Twitter the most egalitarian of the popular services:
Almost 23 percent of Facebook users earn more than $100,000 a year, compared to slightly more than 16 percent of MySpace users. On the other end of the spectrum, 37 percent of MySpace members earn less than $50,000 annually, compared with about 28 percent of Facebook users.
