Pew Internet and American Life Project has a new report out on Teens and Social Media; finding that girls are the leading content creators (excepting video posts), and:
There is a subset of teens who are super-communicators -- teens who have a host of technology options for dealing with family and friends, including traditional landline phones, cell phones, texting, social network sites, instant messaging, and email. They represent about 28% of the entire teen population and they are more likely to be older girls.
It's interesting to think about this through the lens of Mark Granovetter's Strenth of Weak Ties lens. The Internet, and the increasingly social nature of it, is so blatantly a fantastic tool at supporting and expanding "weak" ties.
