On a webinar that I was watching on a phone, the presenter shared a slide with numbers. There were many numbers, and they were small. The same goof-up had happened at a destination conference a few months ago! The text size on the slide was teeny-weeny, and you could not see much, even if you squinted your eyes. This time, the problem was not that the presenter had used 8 point text on the slide; this text was 20 points, and that did not make it too small. Even then, in a large room, you still could not read the text!
