I’m not sure I love this advice on slide design, but some of it makes sense. Much too often I see people putting lots of information on slide decks, as though readers will be studying the slides. I am working to reduce the amount of letters or “data” on each slide, and increase the information by making things simpler and hoping people will pay attention to me.
I do think that larger fonts are important, and I like the idea of color. I hate animations, and prefer to either have everything on the slide at once, or use multiple slides to highlight some change. The changes I highlight, however, are usually images that change rather than words.
