My Thoughts on Reviews

For clarification - a couple of fellow indie authors have experienced some truly horrible remarks and questions in reviews they received recently. I will leave you to make your own minds up about the whys and wherefores, but it prompted me to think about reviews and share some of my own thoughts on the subject.
Just some thoughts on reviews and reviewing. If you want to share your responses then by all means do, but please keep it civil. Thank you.
