How much did the alpha, beta, and gamma readers in your opinion influence the end product [of Oathbringer] here today?
Brandon Sanderson
...I find them invaluable. Let me define them for you first.
Alpha readers are a very select group. My editor, my agent, my wife, and, like, my assistant-- like Peter. These are alpha readers, people who are reading it in a very raw form.
Beta readers are more like a test audience. The difference between alpha reader and beta reader is that the alpha is somebody who's an industry professional, for me, who can say-- can look at the structure and say "here's some advice on structure" and things like this. A beta reader is just a person who likes books, whose job is just to say "I like this, I don't like this, this is why." Right?
Gamma readers are proofreaders. So, usually, Peter handles all the gamma readers. I don't even see what they say, because that's all to fix proofreading.
I am a very big believer in test audience. I know some writers don't use them at all, but I find it really, really helpful to see how people are responding to the text and the fiction, and then looking and saying, "What is it that is making them feel this way? Do I want that? Do I not want that?" It is just a huge piece of the toolbox for me, a huge tool in the toolbox. (That metaphor doesn't work, because a larger tool in your toolbox is not necessarily more useful, but go with me on it.) I would say, they had all kinds of effects. And we might have Peter do some blog posts on things that I changed because of the beta readers while I'm online. And once you've read the book, you can ask me, we'll try to post about some of this stuff. Usually, they're not making suggestions, they're just giving their feelings, and I'm looking for the places where I've misfired. Where I'm like, "I thought this scene would be super dramatic," but everyone is confused. That's the sort of scene you want to find, and then ask yourself, "How can I make it work instead."

You had 70, right?
Brandon Sanderson
Yeah, I had 70 beta readers on this. They wrote around 600,000 or 700,000 words. So, more than was in the book, about the book. Yeah. It's crazy.
