As a presenter, I have noticed that audiences are sending a clear message. They. Hate. PowerPoint. (sigh. or keynote. or whatever.)
Here is a simple chart, from friend and colleague Len Mozzi, clearly explaining the direct relationship of the number of bullet points in your slides to the chance that someone will scream.
I knew this was true, and recently have been doing an experiment. I go one or two slides into the presentation, then blank the screen and actually talk with the audience, rather than talk to them.
After about 5 minutes, I note that the if the discussion does not continue, we will go back to the slides.
We never go back.
Hmm.
