How'd I do? Follow up to last week's TV appearance thread

Last Thursday I asked for advice re: my first TV appearance. That thread is here: http://news.ycombinator.com/item?id=235406 The submitted link above leads to the video of my TV appearance as well as an article I wrote in response to appearing on the show. Last week I received advice about what to wear, say and how to comport myself. All super useful. How'd I do? Suggestions for next time?
