I have taken speech 101 and I'm very good at speaking in front of a crowd I might add =)
I think in order to be a good speaker, you must have confidence in the subject matter you're speaking about. I could get up and give a speech on a boring matter such as insurance and make you think it's EXCITING lol.
As far as Chip goes, I think he displayed a heck of a lot more professionalism than JF. He seemed a lot more sincere even if a little nervousness showed up in his speech.
Now Goldie, if you were in the back row making fun of my speech, I would ask you to come up on the plat form and join me =) Hey, I'm not greedy, I'll share the spotlight.
