WB.SE is unique in the sense that we have a great workforce ready to answer almost anything that drops around the site. This can easily be seem if you look at how fast unanswered questions get a answer - this place is one of the most efficients on the whole Stack.
That said, each one of us can only answer so many questions in a given time.
I really like to help. I would love to be able to give some hints or some direction for someone writing a book or any other kind of media, and see that material taking off.
What I don't like, however, is to spend a considerable time writing an answer to discover a bit later that the asker just asked it because he/she was bored, and the time I spent on his question was basically moot. Really, I could have spent all the time that I spend thinking about that question on something else - my own works.
I could also have used that time to help someone that actually needs help.
Keep in mind that this is not a entertainment site, as much as it looks like. We are here to help people understand stuff, as much as every other other stack around.
Questions asked "just because" take off manpower that could be used on questions that have a legitimate need for help.
If you are just wondering something on the lines "What would happen if..." just to sate your curiosity, you can always use the chat!
I think that if you would use the question for something applicable, that would be the best.
