First of all, lets try and keep in perspective why you're asking a question. Are you trying to see how many respondents you will get or are you looking for genuine answers?
Next what generally is the subject matter of the questions you ask? Has the question been asked before? If so, how often?
Additionally, how is the question formatted? Is it short and concise or does it carry a lengthy and detailed narrative? Does it garner interest?
Furthermore, is it written in a way where a fifth grader can comprehend the content, or does it require someone with an advanced degree to decipher it?
The reason I asked all of these questions is because the way you ask your questions will not only reflect the amount of respondents, but the type of respondents as well. Your answers will also be reflective of those who has some knowledge of the information you're seeking.
Now you also have to remember the bulk of your audience which appears to be mostly in the upper teen to mid twenties group, which will mean more complex questions will net you less responses, not necessarily from lack of interest, but because of lack of knowledge or experience.
Most people (aside from attention seeking trolls), won't respond to questions that extend outside of their knowledge base. Simpler questions, formatted in easy to read and understand wording will net you more answers. The more complex the question, the fewer people will respond, plain and simple.
I can't speak on behalf of anyone else but myself, but I won't answer a question where I don't have any insight to a reasonable answer. I also tend to avoid self centered and/or self serving questions as well as questions where people already have a predetermined biased answer and want their respondents to give confirmation to their biased views. I don't mind complex questions as it gives me an opportunity to exercise my brain as well. I will also answer some opinion based questions.
Different people have different selective processes for determining which questions they choose to answer and which questions they choose to avoid. All of the factors previously stated will be some of the reasons they choose to, or not to answer.
In conclusion, you should be more concerned with the quality of your responses more than the quantity, because you will most likely find the answer in the select few who decide to answer your question as opposed to the masses saying anything just to accumulate points.
