Americans have a "growing comfort level with young people using Internet technologies such as social networking sites, chat rooms and email," according to a new study from the Congressional Internet Caucus Advisory Committee (CICAC) and 463 Communications. The nationwide survey found that 27.7% of Americans said social networking and chat should be restricted to adults, down from 35.3% of people surveyed in an identical study in 2007. As for access to email, 14.7% said people should be adults in 2007, compared to 2.4% now, and for general Web surfing, the numbers were 17.4% last year and 4.2% now. "Despite an evolving comfort level with youth use of the Internet, the survey revealed significant concerns with social networking technologies. For instance, a significant majority of those surveyed, 63.2%, believed that children under 16 years old should not have use social networking sites and chat rooms," the CICAC reports. Many US-based social-networking sites have a minimum age of 13; MySpace's is 14.
