Coming from a little behind in posting assignments :0) this TED talk is given by Chris Anderson on How web video powers global innovation.
Chris's very interesting talk is about how the web has created what he calls "Crowd Accelerated Innovation"
Take a look and see what you think.
This is a good example of how the forces of social media and technological innovation can be put to use as a somewhat educational venue. Good in some aspects a little strange in others.
