Amanda is a popular video blogger on YouTube. She's also severely autistic (you'll be questioning exactly what that means after you watch her video), and she's amazingly articulate for someone who "can't" communicate. Many students struggle with communication, whether because they’re shy or they have Asperger’s Syndrome or some other condition that makes talking or writing a challenge. Amanda has managed to use her blog and YouTube as a way of creating a dialogue with the rest of the world.
I strongly encourage you to take a look at Amanda's video, In My Language, and peruse her blog, Ballastexistenz. What assumptions do we make about others, especially as teachers? And if Web 2.0 tools can allow someone like Amanda to interact with others in their language, what can be accomplished by using these tools in education with our mainstream population?
