We all love power point. We have all seen the impact it can have, both good and bad, over our groups we present to. I was reading a blog the other day and found a great rule to live by for power point (http://blog.guykawasaki.com/2005/12/the_102030_rule.html#axzz0mTnr7Xs4)
Here's the rule
10 slides, 20 minutes, 30 point font.
It's that easy. 10 slides will limit the length and depth of your conversation, 20 minutes ensures that at least SOME of you important information will be attended to, 30 point font will break you from trying to put your ENTIRE speech on a slide.
Don't get me wrong I love presentation tools like keynote, power point, prezi etc. but misusing them can lead to horrible presentations.
