Let's face it, the majority of those threads are created through utter boredom. No-one actually sets out to learn the favourite meats of others, they just start a random topic to create some activity. If nobody cares about the question, why should anybody care about the answer?
I never read those sorts of posts, unless there's a poll (Hint: compulsory polls in every thread), or an actual discussion going on. Sorting through 3 pages of single word replies isn't fun.
