10-20-30 rule for presentations

Ok, I have had this discussion too many times with presenters and presenter wannabees.  The author of the blog is spot on as far as I am concerned. 

Sure, you have a 10-hour OSHA training course - yes, the concept will not work based on what is required.  But I am focusing in on that presentation that we often give.  You know which one – the conference in Chicago, the overview to pastors and wives or maybe that refresher to the maintenance team.  But reconsider the concept that there has to be a slide for every 30 seconds of presentation.  I have not found support for that one.
