I just watched Dick Hardt's oscon 2005 presentation for the first time. He uses the Lessig Method to great effect, which keeps the pace quite perky and the delivery of his laugh lines in time.
Of course, what we really need is an automatic presentation of news using the Lessig Method. So, for everyone as time-crunched as the over-worked techs we are, we now have the News in 90.
Next release will have semi-random highlighting of important words and images. ;)
