Alef:
We must be careful not to turn commenting into an art or a science and scare would-be commenters away.
I absolutely agree, Alef. I know that some of the newer members are under the impression that one has to comment in great detail on every story they read, which isn't the case at all.
We need to make 2 comments out of every 500 stories read. Of course, we hope that readers will comment more frequently than that, as a way of showing their appreciation to the authors. We like to see more than a cursory "good story" as a comment, but an essay isn't required, just a couple of lines for the stories you have particularly enjoyed reading, saying why you liked them.
