– Twitter is booming as a destination for teenagers who complain about too many adults and too much drama on Facebook, according to a study published Tuesday about online behavior. It said teens are sharing more personal information about themselves even as they try to protect their online reputations.

“They still have their Facebook profiles, but they spend less time on them and move to places like Twitter, Instagram and Tumblr,” said Amanda Lenhart of the Pew Research Center, one of the study’s authors

In the poll, 94 percent of teens who are social media users have a profile on Facebook — flat from the previous year. Twenty-six percent of teen social media users were on Twitter. That’s more than double the figure in 2011 of 12 percent. The poll suggested teens are also taking steps to protect their reputations and mask information they don’t want others to see. For example, nearly 60 percent of teen users said they have deleted or edited something that they had published. Just more than half have deleted comments from others on their profile or account.

Researchers surveyed 802 parents and their 802 teens. The poll, conducted between July 26 and Sept. 30, 2012, had a margin of error of plus or minus 4.5 percentage points.
