Power Point makes you dumb.I shit you not, the board that investigated the shuttle Columbia disaster fingered PowerPoint as being part of the problem.
My favorite bit out of this article, though, is:
“… Colin Powell used a slideware presentation in February when he made his case to the United Nations that Iraq possessed weapons of mass destruction. Of course, given that the weapons still haven’t been found, maybe Tufte is onto something. Perhaps PowerPoint is uniquely suited to our modern age of obfuscation—where manipulating facts is as important as presenting them clearly. If you have nothing to say, maybe you need just the right tool to help you not say it. ”
