Discussions about inequality and access to the internet are one thing, but if you look only at people who already have access, are there differences in online behavior? Eszter Hargittai found that race, ethnicity and education level predict whether young people are more likely to use the social networking site MySpace or its competitor Facebook.

TechCrunch points to a study by Hitwise (a marketing company that tracks internet usage) that suggests class, geography and other factors shape whether people use Google or Yahoo! as their search engine of choice:

They include “lifestyle” indicators like “Urban Essence,” “American Diversity” and “Small-town Contentment” that I’m not sure how to react to, and of course, as a private consulting company, it’s not like they’re giving their data away here for social scientists to scrutinize. (Though I admittedly have no idea what it would take to get the data…I got impatient with their website very quickly!) Nonetheless, pretty interesting.
