My anti-Powerpoint rant
Just to be fair, here is a suggestion to help make best use of Powerpoint. Dan Kestin sent me the following suggestions, which he attributes to IBM:
All headlines should be complete sentences (ending with a . ! or ?)
Horizontal logic: All headlines should read together like a story, in order. If you just read all the headlines on each slide, without reading the bottom stuff, you should be able to learn the main messages of the presentation.
Vertical logic: All content on the body of slides should directly support the headline sentence. Further, each slide should stand on its own - and be understandable, outside the context of the rest of the deck. When taken in context however, it should strengthen the presentation of the story
