All the people who are offering solutions are doing it on a volunteer basis. I expect there is a filtering effect - they respond to the questions that they are interested in or which can be handled without doing any special research. If someone out there already knows the answer to your question and can spare a minute to type it in, that's good for you. But if someone has to do special research to answer your question it might as well be you. If it is someone else then it would be only because they are interested in the question too and want to trust the results.

Perhaps the question just isn't interesting enough to guru class.
