I don't believe that Powerpoint *is* an effective way of presenting very much at all.
Really? In its most simple form, Power Point can show pictures. You would expect me to believe that pictures aren't an effective way of representing something.
But the way Power Point is generally used means that any useful or memorably information that might have been put across that way is diluted to nothing. You get far, far too many slides and way too much text for it to be effective.
