Conventional wisdom says that teens dominate social networks. Not so. The oldies are crashing the party. The vast majority of those who frequent these sites networking sites are over 25 years old, according to comScore.
OK then. Social network sites must then be about being social, right? Again not so. According to new data from The Pew Internet Project & American Life Project, some 55% percent of teens who publish to these sites do so through restricted profiles and pages. Further, 66% of teens who are socially networked have their profiles blocked from view by anyone but their friends.
