Here's a novel concept: a dense deck of PowerPoint slides is just as not-fun for the presenter as it is for the audience.
I guess we've always known this is true in the back of our minds; but if a presentation wasn't fun to present, why would a presenter present it? (Ladies and gentleman, your new tongue-twister.)
We stumbled upon this revelation (ehhem) when consulting with a client about their lunch-and-learn style presentations. They wanted a fun, brain-based presentation that was turnkey; anyone presenting could give a good, engaging presentation--even if they weren't their top choice for a speaker. Then our client said, "Well, if we have a fun presentation, it could make the presenter better. After all, presenters like presentations that are fun to present."
The lightbulb went on!
We're so entrenched in advocating for the audience to be engaged, that we forget that a speaker can become a talking zombie; someone who is just delivering the words and going through the motions without enjoying the experience. The presenters' enjoyment always took a backseat to the audience--and we went forth crafting energizing, brain-based presentations without being aware of the effect it had on the presenter.
It's true, there are some presenters who can make a proverbial silk purse out of a sow's ear--taking a 49 slide deck with 18 bullet points per slide and presenting it in an energetic way. . . but they typically aren't just *presenting*, they're also engaging with jokes and anecdotes and going off the slides, etc. If you had to substitute speakers at the last moment, giving that same presentation wouldn't be nearly as agreeable.
Just as the audience doesn't want to listen to a speaker just reading slide after slide, we can't imagine that that's what speakers want either. Not only does it not provide a creative outlet for them, but not having a presentation that engages the audience deprives a speaker of the critical positive audience feedback--the effervescent bubbling of energy in the room that you feel on stage when you're really *on* and they're really liking what you're saying.
So I guess the point is a humanitarian one: don't just improve your presentations for the sake of the audience, do it for the presenters, too.
