Nancy Verbrugghe gives a presentation on how to avoid "Death by PowerPoint" and instead give engaging presentations. She notes that 95% of presentations are boring and contain too many slides with too much text and bullet points. She recommends preparing well by asking questions and writing a handout, designing slides simply with good contrast and empty space, and delivering concisely while engaging the audience with stories and emotions. The key is to signal the important messages with a high signal-to-noise ratio and stick to the main points.
