The first TED Talk I watched was given by Ziyah Gafic, who talked about the victims of genocide in Bosnia and the everyday items they carried with them. He discusses the "mundane, everyday objects" that they carried with them such as combs and keys because "they had no idea what was about to happen to them." Gafic tells us how these everyday items can be used to identify the bodies and victims of these crimes and wishes to see no victim left unidentified.
I believe Gafic was very effective with his speaking. It certainly helped that he had interesting information to present, but it was the way he presented this information that really brings it home. Gafic is very effective with his hand motions, using his hands to add to his speaking. He keeps his hands moving in a way that almost allows him to speak with his hands. It makes it pretty easy to see that he is very comfortable up there speaking to his audience. Some people who are uncomfortable with speaking may fidget with their hands or just put them in their pockets, which takes away a bit from their speech. Gafic is very good about moving his hands and using them to almost add an element to his speaking. Another big part of his speaking, possibly the most important, is his use of visual aids. He presents many images of everyday personal items that were carried by the victims. The audience is able to see exactly what he's talking about and can see the variations between these items and how they can be used to identify victims of the genocide. This provides the audience with a clear image of these items that we may take for granted but were quite valuable to these people.
The second TED Talk I viewed was given by Terry Moore. This talk was about how to tie your shoes. Yes, you read that correctly. It's ridiculous to think that people paid a lot of money just to see a man tell them that if they simply go the other way about the loop, their shoes will be better tied. His speech was not exactly brilliant. His speech was plagued with stuttering and he was a bit awkward with his hands.
