A colleague just forwarded me the video of your talk. Perhaps your friends will unite in telling you it was wonderful. For me, it wasn't. I will be stunned if it makes the cut for the TED site. I know I *love* great talks and lectures. I love great teachers. But for me this was boring. My wife had the same reaction.
I only went through it once and could have missed something, but I think a huge deficit was you did not tell even one story. A great story, especially a personal story in which the speaker shows vulnerability and learns something, is especially effective in a TED talk.
