Bests & Worsts Reviews from Amazon

I used my free trial month for Kindle Unlimited to download this book, and am glad that I did not pay for it. The facts that the document presents are: Only a tiny minority of Amazon's ebooks are included. Authors have to agree to include their books in the service, and many of them are self-published by little-known authors. Self-published works vary in quality. People who hope to use the service to read hot best-sellers will be disappointed, while those who like to read lots of books by authors not-yet-famous may come out ahead. Students who need to download study guides may find it cost effective. The rest of the document is unsupported opinion. I admit that I am an unrepentant grammar snob. So it amused and annoyed me that the author decried the poor editing of many self-published works, even though this brief document has several grammar and usage errors.
