And in contrast to my last post… “Specifically, 19% of teens who created a Facebook profile said they are spending less time on the site than they did a year ago, or have stopped visiting it altogether, with the largest group — 49% — saying their use began falling off within the last three months (29% in the last month)… 16% of respondents who left Facebook or use it less said they did so because their parents joined, while 14% said they did so because there are “too many adults/older people.””
