Pew Internet & American Life Project released its latest report on U.S. teens' online behavior in terms of content creation and consumption. Half of all teens have contributed to the proliferation of WWW: they create a blog; create or work on a personal webpage; create or work on a webpage for school, a friend, or an organization; share original content such as artwork, photos, stories, or videos online; or remix content found online into a new creation.

Some highlights on teen blogging:

Teens are early adopters of blogs: 19% have created their own online journal or blog and 38% read them. The numbers are translated into four million teenage bloggers and eight million blog readers ages 12-17.

Older girls lead the blogging activity among teens: Older girls ages 15-17 are the most likely to blog; 25% of online girls in this age group keep a blog, compared with 15% of older boys who are online. About 18% of younger teens of both sexes blog.

Frequent Internet users are more likely to blog: Teens who go online frequently are more than twice as likely to blog; 27% of daily users have their own blog, compared with 11% of those who go online several times a week, and 10% of those who go online less often.

Teen bloggers are tech-savvy: Bloggers and to a lesser extent teens who read blogs are a particularly tech-savvy group of internet users. They have better access to technological tools such as cell phones and PDAs and are more likely to have their own computer at home and use it in a private space. They help adults do things online. Most strikingly, they have more experience with almost all online activities that we asked about.
