Sometimes questions get marked as a possible duplicate and they get closed before the OP has a chance to explain how their question is different from others that seem to be similar. Currently when the first user issues a Vote to Close as Duplicate, a comment like this is auto-generated:
Does this answer your question? What is a generic question?
At this stage it is not immediately obvious that any kind of moderative action is being taken on their question. New users may not be aware that their question will be closed if not corrected based on votes by community members, nor that they have an opportunity at this point to intervene and prevent this.
I would suggest enhancing this auto-generated comment to be something like the following blurb would be a more user-friendly way to inform new users of how the site functions, and give them opportunity to intervene sooner:
This question has been marked as a possible duplicate. Please show how your question differs from those already asked or it could be closed based on votes by the community. Does this answer your question? (link to similar question)
What is the procedure for evaluating and instituting such a change?
