SlideWe’ve heard the rules for using PowerPoint effectively:

  • 7 lines per slide
  • 7 words per line
  • No flashing animation

Not bad guidelines, but they fail to affect the key problem behind PowerPoint presentations. Slides should not provide a kind of closed captions for your talk or a repository for reams of data.

As this presentation demonstrates, PowerPoint works best as a backdrop to a speech. Use it for images, simple figures, and emphasis. Then leave it in the background and talk to the audience.
