At one time or another many of you have see the PowerPoint version of Lincoln's 1863 presentation. (They called them speeches back then.)
Here's Peter Norvig's background rational for its creation and what followed after its release:
"Why I did it
"Doesn't he realize this presentation is a waste of time? Why doesn't he just tell us what matters and get it over with?"
How many times have you heard (or muttered) that? How many of us have been frustrated at seeing too many presentations where PowerPoint or other visual aids obscure rather than enhance the point? After one too many bad presentations at a meeting in January 2000, I decided to see if I could do something about it."
