Normally if anyone asks a question and there are no answers it usually stays up the top of the page - if its a relatively new question. Many people get to see it and the possibility of getting a good answer is huge. However, some people post incomplete answers, or answers that do not solve the problem. In that case the question is pushed down the main SO page ( within the tags ) and people tend to ignore it assuming the question has already received an answer ( accepted or not ). So my concern is: what can I do ( besides placing a bounty ) to receive more answers/views on my question?
Questions that have got only 0 score answers are still highly visible in the Unanswered tab and should get the attention you need. Alternatively you can flag (and eventually delete) incomplete or very low quality answers. Also remember that Community (the SO bot) randomly pokes old unanswered questions every hour so they get some attention.
