Why is WikiAnswers not answering my question?

The questions on WikiAnswers are answered by online citizens on a voluntary basis. They answer the questions that they want to, when they want to. And although there are a number of people that look through the unanswered questions for the purpose of answering them, there are a lot of unanswered questions that exist and new ones being asked on a continual basis. Also the proper placement into the category that is closest to the question can have some effect. If a question is in the wrong category perhaps it is not visited as much as it would be if it were in the right category. And then there is always a chance that a person may ask a question that most users do not have the answer to.
