If you are a writer, ask to be paid for your work. If you are asking a writer to appear, pay them. If you read a book, pay for it. If you accept a free book, post a review. Anything else is eroding the careers of writers everywhere.
This post, from several days ago, is in many ways about writers helping each other and notes that many people–including those on writers’ Facebook friends lists or who follow their blogs–sign on to accept a free copy of a book but then never read it, much less review it.
As Hope Clark mentions, it’s bad enough when a reader requests an ARC (advance readers copy) and then never posts a review; it’s worse when another author does it. An Amazon-style review can be posted in a few minutes and it can make a big difference between the success or failure of a mid-list or an emerging author’s work.
We need to help each other and keep our promises.
