Pew on Social Networks: 7 out of 10 teens have non-public profiles

The Pew Internet and American Life Project released data from their recent survey of teen Social Networks
In the study, it is reported that 77% of teens have a profile available online, but 59% of teens restrict these profiles to their friends. This means that only 3 out of 10 teens have a profile that is "open" to be viewed online.
The report includes some valuable summary statistics, including the following I found interesting:
55% of online teens have created a personal profile online, and 55% have used social networking sites like MySpace or Facebook.
37% of 12 and 13 year olds have SNS profiles.
Seven out of ten (70%) online girls 15-17 have created a profile, compared with 57% of older boys.
Almost half of social network-using teens visit the sites either once a day (26%) or several times a day (22%).
Interesting remarks about this report:
