Query: Well-organized, easy-to-read primer

This book contains a lot of helpful tips and techniques on how to improve your skills in public speaking, presenting, and interviewing. While it's true the book focuses on the basics, it is a well organized, easy-to-read text that will be immensely useful to beginners and a nice refresher to experienced presenters. Since I am somewhere between the two, I found it to be worth the read, as I continue to enhance my own skills.
