PowerPoint Is For Sissies
All right, not for sissies, exactly, but it's being done to death. PowerPoint Makes Everything Really Important in a Telegraphic Way. That's Fine in Some Cases, But It Gets Tiring When It Happens Too Much. Besides, PowerPoint is the triumph of the quick "fact" over the art of argumentation. And a lecture is, or should be, a kind of argument. It's more, too -- a chance to observe a voice, a body, a brain, and a personality engaging an audience with similar interests. If you put your bulleted ideas up on slides, your audience will look at the slides, not at you. You'll also be teaching them that What You Have to Say Can Be Summarized in a Few Words. Can it?
I guess I violated this rule a few times.
