This is a great TED talk, today. I love the idea of exploring what tech is available to enhance and help us tell our stories. If this talk doesn't inspire you to create using social platforms--I don't know what will. :)
Andrew Fitzgerald works at Twitter, so he's very knowledgeable about the medium.
I actually believe that we are in a wide open frontier for creative experimentation, if you will, that we've explored and begun to settle this wild land of the Internet and are now just getting ready to start to build structures on it, and those structures are the new formats of storytelling that the Internet will allow us to create.And then he gives examples of storytelling through twitter.

Having fictional characters that engage with the real world? What a cool way to use twitter. What would your characters want to say to the world? Have you considered using social media to explore creativity?
