- Distance you from your audience as the slide becomes the communicator.
- Make simple complex because bullets take over from narrative.
- Distract from the core message because of special effects.
- Remove your value as you are -literally-side-lined.
- Remove impact as you allow the audience to read ahead.
- Make you 'one of many' in using a slide-deck.
- Reduce your flexibility to adapt because of a pre-organised set of slides.
