The Pew Research Center for People and the Press, in association with the Pew Internet and American Life Project, just released some interesting stats on how Americans are using social-networking sites to learn about the presidential campaign.

The survey, conducted in December 2007, found that 27% of people under 30 have gotten information about candidates from social-networking sites such as MySpace and Facebook. Nearly one-tenth (8%) of people aged 18-24 have signed up as "friends" of presidential candidates.

The story's different thirty-somethings: Americans between the ages of 30-39, although they're increasingly signing up and using Facebook and MySpace, aren't using these sites to find campaign information. Although 21% of Gen X-ers in this age group use social networking sites, only 4% have gotten campaign info from them, and only 3% have friended a candidate.
