Good tips. I agree one of the worst things is to read from your slides. Anyone wants to see the best watch Gore!

The other thing I tell people (I am biased of course as I do presentations professionally, is to use a pro to actually design their presentation.

Sorry but most people have no clue. They use every transition in the book, they put text on the screen in 12 pitch, they mix up their fonts and font colours, they have stuff flying all over the screen, and their page is filled to the brim with no white space. Or they import a 12 megabyte image without reducing the file size and then wonder why their pages take so long to appear. I have seen it all. In my whole life I have seen just a handful of truly good presentations. It is getting better though, as people become more comfortable with the tools and better educated.

My company, eyestir does a lot of work with people who have a presentation but want us to make it better. Usually they are so bad we have to redo them from scratch. A government manager + PowerPoint = disaster. Get some help, that's my advice.
