I want to know the answer to the following question:
What surprising feature does youtube possibly have the chance to revolutionize?
All the background I'm provided with is that "Observing that face-to-face communication of the type that online videos convey has been "fine-tuned by millions of years of evolution", TED curator Chris Anderson referred to several YouTube contributors and asserted that "what Gutenberg did for writing, online video can now do for face-to-face communication".". Is that enough to answer the question?
