Lee Miringoff, director of the Marist College Institute for Public Opinion said, "we're in an era of information. Some people are concerned, reluctant and skittish about the extent of online information. There's a privacy element that some people feel is getting lost."
Privacy in social networking sites is a much discussed issue now a days.
Some sites like Facebook recently had changed its privacy policies to give users more secured profile and it also had provided more control over their content that go public.
The poll showed that 27 percent of the 1,004 people who took part in the survey were concerned about privacy on social networking websites, and a further 23 percent were very concerned.
Young people have more carefree attitude about the sites and their privacy in it but older Americans are more worried about the issue.
