In the interest of fairness, I'll just get this out of the way up front. Amanda Luedeke is my literary agent. She's a big part of the reason that I'm published and she's great at what she does. What makes her unique is that before she became a literary agent, she was a marketer, a subject that usually gets most authors tied up in knots. For a while now, Amanda has been doing regular posts on marketing at Chip MacGregor's blog. Well, now she's gathered all of that advice together in one easy-to-read place: The Extroverted Writer: An Author's Guide to Marketing and Building a Platform. It's a short book, easy to read, and easy to digest.
Amanda covers a diverse range of topics, like how to use Facebook or Twitter efficiently, what you should blog about, and what should be on a website. Unlike a lot of marketing books, this isn't just empty cheerleading, she gives practical advice with good suggestions on what to do.
If you're an author, either published or not-quite-there-yet, this is a good resource for you to have. I'm sure you'll get a lot out of it. Although you may not have the experience of hearing Amanda's voice in your head while you're reading it. LOL!
