I think it might be an intrinsic component of human nature to listen to others tell stories more than to tell our own.
And if this is true, why are there so many weblogs?
Why do people keep photo albums?
Why do we love to talk on the phone with friends and family?
I think these are all acts of “storytelling” that are simple, personal, and powerful. Those three criteria are probably reasonable criteria for a storytelling device that can change the world. The phone (and now mobile phones) is probably the single most powerful device. The camera has played a profound role as well; why do you think people are working to combine these things. They let us tell the story of our lives in the most personal and profound way possible, right now.
No. We are all storytellers. It’s just a matter of how we like to tell our story.
