If non-technical speakers spent less time faffing around before the session making awful looking powerpoints, and more time learning how to speak engagingly, the world would be a much better place.
This said as an Audio/Visual Operator who has spent hundreds of hours at a sound-desk watching technically inept speakers fail to impress - no matter how flashy the animations.
The worse thing over the last few years is 'Prezi'. It's a powerpoint alternative which ostensibly makes it easier to make awesome looking graphics.
The 2 problems with it are that it's a hell of a lot harder to actually present on a second screen, so you end up having to drag windows around, and that speakers are still under the impression that because you have swooshes and zooms and text folding inside other text, suddenly it's more likely for people to find the presentation content interesting.
The trouble with BAD technology, is how do you fight it? The normal way is by competition - making better tech. But when the concept itself is wrong, but somehow culturely accepted...? Any ideas?
