“Blue-collar, part-time workers might like the appeal of MySpace more — it definitely depends on who you meet and what they use; that’s what motivates people to join and stay interested.”

Is there a class divide online? Research suggests yes. A recent study by market research firm Nielsen Claritas found that people in more affluent demographics are 25 percent more likely to be found friending on Facebook, while the less affluent are 37 percent more likely to connect on MySpace.

More specifically, 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.

Even on social networks, we can’t escape class distinctions. Marketers interested in connecting with Middle America should be taking a more active role on MySpace instead of reaching out to the ‘vastness’ of FB.
