How can you get people to answer the question you are actually asking?

So, I just asked this question: http://www.fluther.com/94469/

I specifically ask to propose a current situation, and all of the answers are about how it has happened in the past. I know that it has happened in the past, that is not what I’m asking. I want to know if it will happen again and under what circumstances it will.

Is it a bad question? Was I unclear in some way? I guess I get frustrated when I’m interested in something and would like to have a discussion about it and the discussion gets hijacked.

I’m looking for advice/guidance.
