In response to a recent scuffle between a Goodreads reviewer and an author, BookRiot offers this advice to authors:
But it’s not just the one-or-two-star reviews. I also don’t think authors should respond to positive reviews, even to say thanks — the dynamic is too weird. Perhaps not all reviewers feel as I do, but I think the reviewing space needs to be its own thing, unadulterated by the feeling of the author’s hot breath on the reviewer’s neck as they try to make an honest assessment of the work in front of them.
