As someone that has to do a lot of presentations, I absolutely loved Don's advice.  His take on not relying on the slides, and engaging the audience are (I'm afraid) all to often ignored in so many of the presentations I watch.

Another person that does excellent presentations and embodies all of what Don says in this video is Prof. Lessig - his presentations are legendary (just the white typewriter text on a black background is his "signature").  I've found it really hard to find his talks online, but if anyone want to view an excellent example visit

Please, please, please, take the advice of Don (and learn from other people of what "works) - these type of people make going to a talk an enjoyment, not a drudge.
