As an aspiring author, I obviously read a lot. I like to give recognition to authors who write good books and like to share the great finds, so I'm thinking of starting a simple blog to post reviews, as well as Amazon and Goodreads. I only plan on reviewing the books I like enough to give 4 and 5 stars, but I'm afraid I'll still somehow make enemies or hurt my future as a writer. Do other authors write book reviews? Is that a thing? Does anyone here both write and review?
