It’s the story, stupid. Don’t let presentation software keep you from getting your story across. ~ Doc Searls
Maybe a bit harsh in his delivery but the point is spot on!
We all glance and grab™ crucial information every day making critical decisions fast. Why not help your audience do the same? Use images to tell your story or make a point and keep text telegraphic. This strategy will allow your audience to quickly glance at your PowerPoint, grab what they need and keep their attention where it belongs — on you.
