Powerpoint isn’t inherently evil, but the here’s-my-slide-notes-for-me-to-read-out-loud-to-you approach that it supports is. A good rule of thumb for Powerpoint is to use it as little as possible — a single slide should match at least 3 minutes of explanation. And it’s OK to put the slides on hold if you have a better way to explain something. For a good thrashing, see Edward Tufte’s article “Power Corrupts; Powerpoint Corrupts Absolutely” in Wired and probably all over the web.
