A new report from Pew finds that teenagers are increasingly sharing information about themselves on social networks. Some numbers from the report:

• 91% post a photo of themselves, up from 79% in 2006.
• 71% post their school name, up from 49%.
• 71% post the city or town where they live, up from 61%.
• 53% post their email address, up from 29%.
• 20% post their cell phone number, up from 2%.

Also in the report: 95% of teens use the Internet, and a whopping 81% of them use social media sites, the most popular of which is still Facebook (though Twitter and Instagram are making up ground).
