Criticizing the Critics

I write ebooks, I do so for fun, as do thousands of other people around the world. I usually write erotica stories. Sometimes, I look at the work of other authors, to see what others in my industry do. Sometimes I read the reviews of the ebooks others write and I have been amazed at the vulgarity, rudeness and aggression of some reviewers - all over a product for which they paid 99 cents!
