TED Talk speakers are generally known to be effective public speakers.
What are some mannerisms or things
you notice about this speaker that
makes him/her a good public speaker
or a “not so good" public speaker?

Things that I notice are that they're confident when they're speaking. The topic that they chose is something that they are very passionate about. Their confidence is something that gets the crowd more engaged. I also notice that they also have humor in their TED Talks, That can really help the audience more engaged as well and it also shows that sometimes it's ok to have some fun here and there. One bad and good thing that I notice is that sometimes they're really sweaty when they talk and that may not attract the crowd a lot of the times. It's also a good thing because it just shows that they're working hard. Overall I think that public speakers are good(most of them)
