  1. This video definitely focuses on a really interesting argument, and I’m impressed at how detailed you were in your evaluation of his speaking techniques and body language. While I think that the speaker did a great job engaging the audience, there were a few parts in his presentation that I found distracting. For example, at some times, he spoke in phrases, and he took a few seconds to pause between these phrases, making it slightly difficult for me to connect them and understand the point he was making. Other than that, however, I think that the presentation was performed really well, and the topic at hand was well discussed.

  2. You did a good job analyzing the presentation of the speaker. There are a lot of hidden things that presenters do that most people do not pick up on. I think to make your analysis better, you could include how each thing the speaker does makes the audience react.

  3. I absolutely love this topic. I didn’t watch all of the video so I will just tell you my thoughts on just the 10 seconds you mentioned. He loves to do the Italian finger thing. I don’t know if it really helped his argument or if he didn’t know where to put his hands. This is just the first impression I got when I saw only the 10 seconds. I think it’s interesting to see what other people’s perspective is on just the part of the video where it is suppose to be analyzed before watching the entire video.

  4. As you mentioned, keeping a good pace and matching flow of his hands with the speech are both symbols of calmness. People tend to trust and listen to the people who are confident, calm and humble. He himself is definitely one of the most authoritative figures in the field. However, he established more authority when he said the word ‘us’. This is a really interesting topic and I think by exploring the effects of background and images used will make your article even more well-rounded.

    1. I didn’t even realize how his calm attitude added to his presentation. It was so subtle and fit in so perfectly with his topic that I didn’t recognize it until you pointed that out. I like how he fit that in to match the topic of his presentation.

  5. I was totally in to this video while I was watching this. Though he uses very interesting topic for his speech, I cannot deny that his speech skills that you listed contributed highly in making my concentration on this video increase greatly. The most impressive ones were his comfortable eye contact and use of gesture. His stable voice and eye contact make him seem not nervous at all, and thus making no disturbance to people listening. Also, the gesture he uses makes the audience to focus more on his speech. Overall, I think you did great job on catching various speech skills he used.
