Pointless?

You should be so lucky. It's likely worse:

Powerpoint presentations, beloved of the business executive, are so ubiquitous that there are even PowerPoint presentations on how to do a PowerPoint presentation.

Now research claims to have proved what millions of bored workers have suspected all along - they have little power and even less point.

According to the report, the brain cannot cope with having too much information thrown at it at once.

Having someone speak and point to a screen full of facts and figures at the same time causes it to switch off.

The study, at the University of New South Wales, branded PowerPoint presentations a disaster and called for them to be scrapped.

.... "If you have ever wondered why your eyes start glazing over as you read those dot points on the screen, at the same time words are being spoken, it is because it is difficult to process information if it is coming in the written and spoken form at the same time."
