Honestly, I've never deliberately asked a question expecting no or few answers. But I've come to realise that that's the normal response for my questions.
Not at all. After ten years of AB and AM, I sorta keep a mental journal of what kind of questions attract the most answers. I have concluded it is totally random. It probably depends on the weather, the tides, the phases of the moon and other factors that are immeasurable. Machts Nichts.
