Do you ever use PowerPoint while presenting? Dude, read this book. You'll be doing all of us a favor.

Seth Godin's ebook is 10 pages and costs $1.99, which I think goes to charity. People, for less than a cup of coffee you could be reading this thing. You'll probably be done in less than an hour from now!

But for the rest of your life your presentations will be better and your audiences will forever more benefit from your presentations instead of belittling your skills. Which, let's face it, is what they are doing now.
