Using Youtube for public speaking

I recently reviewed heaps of videos on youtube to learn from the best speakers in the world. I had never come across motivational speaker Les Brown before but I'm so glad I did. Wow, what an inspirational speaker he is. Check out some Tony Robbins videos as well. Also don't forget to have a look at some Toastmasters International Contests. These speakers have gone through several competitions to get to the final so they are good!
