Actually, the article is not all one sided -- it does also discuss some
times when they feel that PowerPoint *is* useful.
The whole *point* of PowerPoint is not to educate, but rather to
*persuade*. Its *goal* is to make the audience stupid and prevent
them from looking beneath the nicely-presented bullet points on the
slides. If you don't believe me, talk to people involved in sales and
see how they use the word "powerful" -- it means "words that cause
people to act [in the way you want them to]". PowerPoint -- to make a
powerful point.
(OK, I've calmed down now...)
