As I understand it you only make money if you get traffic to your questions. My questions don't seem to get all that much traffic, so I don't think it would be any advantage to me. Similarly, I don't think making up useless questions would increase income either, but maybe I have no idea what questions are useless. Some questions I think are dumb get a ton of responses. Aren't they planning on moving all questions to subdomains anyway? I think I'll just wait till they do it for me.
