The 10-20-30 rule of powerpoint presentation

I am appalled many a time by the Powerpoint presentations that attack the audience sensibility and I wonder how the presenter could be so insensitive as to not think of the needs of the audience. The font sizes are small, the entire slide is packed with text and on top of it, the presenter insists on reading the whole stuff. Sometimes the presenter goes near the screen and starts pointing out the words or phrases. All this turns out taxing for me and I guess, for many like me.

I came across a very apt piece on presentation that I have followed and found useful. Please follow the link: http://blog.guykawasaki.com/2005/12/the_102030_rule.html

It is interesting to read, easy to follow and effective in outcome.
