If you buy a copy of Seth Godin’s new book Free Prize Inside (which I just got, and it looks terrific), you can get a free copy of his pamplet, “Really Bad Powerpoint.” Which, by the way, is really about how to AVOID really bad Powerpoint.
The not so hidden secret is that the Powerpoint pamphlet is really free for downloading, whether or not you buy the book (but buy it, you should, for your own benefit!).
If you do presentations – especially ones aimed at convincing folks of something – it’s a must.
