According to this new Edison Research study, consumer use of social networking sites is not just a youth phenomenon. While nearly eight in ten teens and 18 to 24s have personal profile pages, almost two-thirds of 25 to 34s and half of 35 to 44s also now have personal profile pages. The study also shows that 30% of Americans age 12 and older, who have a profile on at least one social networking Web site, use those sites "several times a day" compared with only 18% one year ago.
