This article from the Economist.com looks at some students who are using social networking for learning (as opposed to all the other things they could use it for.

Here's great quote:

The high schoolers took a more direct approach. They felt that world peace cannot be obtained without global understanding and respect. Working with a German foreign-exchange student, they decided to collaborate on music composition with students in Germany, entirely online. They “jam-glued” a collaboration site for use by all participants. If they could compose together, they can understand each other better. Collaborative understanding = world peace.

Learning was fun and inevitable. And is ongoing.Economist.com

The question for me is this:
What happens when students actually have a voice?
What would say? And how? And to whom?
