Last month I tried, for the first time, to go with the <i>Presentation Zen</i> thing, and I think it turned into one of the best presentations I've ever done.<p>On the other hand, one key person from the audience has asserted just this morning that I failed to tell her a piece of information that is critical to her. I remember saying it, and it's right there in the notes for the relevant slide.<p>But boy, do I wish that I had a slide with bullet points on it, so I could show her: "Oh yeah? Well, what's this?".
