Terrific Advice
I've been teaching public speaking and presentations for the past six years, and I agree with every one of your points. I arrived at all of them myself without having to read any theory books. All one need do is remember what one liked and disliked when watching the presentations of others. The great thing about your article is that it's so concise and doesn't miss a point.
I would be a little more explicit about outlawing any complete sentences (correctly spelt though they may be) unless it is crucial that they be complete sentences.
If the presenter knows the presentation, there is no need for a complete sentence, there is no temptation for the presenter to read complete sentences from the slides to the audience, and there is no temptation for the audience to read the presenter's complete sentences.
The first time I taught a presentations class, I used ten slides with three or four words or phrases on each slide. That took me about 15 minutes to create. I spent 47 minutes presenting that material. I knew exactly what I wanted to say even though I hadn't written down a word. Each of my words and phrases triggered a brief and spontaneous discussion from me. I think that that's the way presentations should be.
