it's had 1400 viewings but no comments so far, bar one to my email address from someone who wanted what I described, so your observations would be welcome
It is a problem. I have a story that has had 350,000 reads and less than 100 comments. I have another story that has been up for over a year and still no comments. The situation has changed my personal habits. If I read a story, I leave a vote and a comment... never without my signature.
