"96 percent of teens use social-networking tools".

Came across this article from eSchool News Online journal that I subscribe to:

Survey reveals schools have a huge opportunity to harness technology for instruction

Interestingly, students report that one of the most common topics of conversation on the social-networking scene is education--suggesting that schools have a huge, but largely untapped, opportunity to harness these technologies in support of student learning.

I have generally found eSchool News Online a worthwhile read during the course of my study of eLearning.
