I came across this talk by Seth Godin at the 2008 Business of Software conference.
Besides the great content and insights that Seth Godin always puts out, there are two things that I found incredible.
The first is his style of delivering the content. There was a lot of impact to the way he speaks, taking up the whole stage, moving about, waving his hands, etc. It conveys a lot of energy and energizes the audience. He also moves from one point to another quickly, making it worth his time and yours. It also is done on the assumption that the audience is smart, and can keep up with him. It keep the audience one their toes, alert and thinking all the time.
The second thing nearly blew me away. It came out when at the end he talked about some ideas he was working on at the time, yet to be released. He asked the audience to not take photographs or blog about it. And jumped into telling them about his new idea, establishing a new level of trust. The amount of commitment he shows to his audience is fascinating: you have come to hear me talk, and I am going to do everything I can to make it worth your while.
