A reasonably long, and sometimes bitty, article on social media’s use by teenagers and tweens over at MediaShift . Media Usage::Finding Balance in Teen Use of Social Media | PBS. One comment that stuck out as I scanned it,
Kids and teenagers have very little freedom in the real world. Itâ€™s not like back in the day. They used to bike places on their own â€” now itâ€™s all controlled and sanitized.
The online world is the only place where they have freedom of expression, and can really be on their own and be themselves.
