Not sure if this thread is still being followed, but I wanted to add my thoughts on reviews.
I too am amazed at the number of people who read and don't review, but still the number of people I have had reading my stories has thrilled me. I am still just a new writer and I must admit I do take note of what a reviewer says, whether they have liked the story or not. I also try to reply to my reviews, thought I really don't know if the reviewers read my replies. It just seems the polite thing to do.
I have found the reviews in general very positive and they certainly have made a difference in how I write. I sit down now with my idea in my head but also a better notion of what the reader might be looking for, though I know everyone is after something different.
As to writing reviews, since I have begun sending my stories in, I have tried to write more reviews. I really love this site and the freedom it offers to both new and established writers to have your work published but still be allowed your privacy.
Thanks
