I’ve mentioned beta readers several times and I’ve had a handful of people ask me what the heck they are.
It’s like beta testing a product. When you develop computer software or hardware, you have to beta test it before you start to sell it for real money. There will always be coding issues that need to be fixed, so developers have to debug it so that users don’t waste their hard-earned cash on something that’s going to have issues.
Same thing with books. It’s a product, and my readers spend their hard-earned money on it, so I don’t want to sell them a product that is defective.
But how can a book be defective?
