Effective Power Point

I always wonder how technology has spread so much to allow even the most untechnichal person, access to the most advanced devices and techniques but how often they don't even know the basics of that technology.
Take MS PowerPoint for example. There is a complete culture and economy around that software that includes meeting rooms, projectors, laptops, notebooks, desktops, cordless mice, screens, etc., etc., etc.
But have you noticed how little attention is so often paid to the most important part of all that: the presentation content itself !!!!
It looks like people think that the technology is so amazing that it by itself will take care of making the presentation good no matter how it is made.
But that's no true !!! There are some basic rules that must be observed in order to achieve an effective message transmission, which is the really important thing there.
