I always enjoy reading about how to improve my presentation skills. And PowerPoint always seems to come up.
Power corrupts. PowerPoint corrupts absolutely. PowerPoint is evil.
Did Lincoln use PowerPoint to present the Gettysburg Address?
PowerPoint may have caused the Columbia disaster?
Is PowerPoint the devil?
Things that Microsoft does not want you doing with PowerPoint.
Does PowerPoint make you stupid?
And, my personal favourite, and one that I wish lots of people would read, Really Bad PowerPoint.
