Social Networking: In. Blogging: Out.

Teens and young adults are moving away from blogging and using Facebook and other social media sites in increasing numbers, according to a recent study from the Pew Research Center.

The Pew Internet and American Life project studied their social media and Internet usage, and the findings revealed that, while those over 30 are blogging away steadily, fewer teens and young adults 18 to 29 years old are writing or commenting on blogs. Instead, 73 percent of teens are using social networking sites, up from 65 percent in 2008, along with 72 percent of young adults. About 47 percent of online adults are on social networks. While older users are more likely to be on the professionally-oriented LinkedIn, younger users are into MySpace. Young adults and those older than 30 are equally likely to be on Facebook.

Perhaps most surprising is that teens aren't into Twitter. While a third of young adults tweet, just 10 percent of those under 18 use the application.

Federal agencies are jumping head-on into the social networking world, using Twitter, Facebook and MySpace to recruit young employees, release new information and communicate with the public. Perhaps this research will help them better understand their audience and target their campaigns accordingly.
