Required viewing for Speech 101: Don McMillan of offers this wonderful overview of common PowerPoint mistakes. I strongly recommend watching the higher-def version on McMillan’s website. Don’t look on YouTube; McMillan is apparently picky about his copyright and doesn’t cotton to unauthorized recordings draining traffic from his website (and hey, can you blame him? A guy’s got to make a living!).

Remember this when you crank your PowerPoints for class or for real life—your audience will thank you!
