Megan Whalen Turner on not-telling.
...I am always tempted when I am lurking to stick my oar in, but I still worry about authors getting in the way of readers. I never have joined. I comment from time to time, so Sounis will know I am around, reading, but I try not to be intrusive. I want people to think for themselves because I like thinking for myself. (I butted heads with an English teacher once when he tried to tell me that the ghost in a short story was just a hallucination. He had a lot of textual evidence. I didn’t care. It was still a ghost for me.) I would never want a discussion to stop because someone, somewhere, found what I said was the “right” answer.
