"skill"? That's bullshit, you can't tell anything about skill from a person's poorly phrased question. Especially since that person's primary language might not be English.
In fact you can tell a lot about what questions people ask. The more specific and detailed a question is, the better the person knows the topic. A skilled language learner would never ask "What is the best way to learn English?" because he knows already that there is no best way, in fact there is no single way. He knows that he needs to combine different methods and which are the common methods and how well they work for him.
By recognizing a misconception that people have at a certain skill level you can guess their skill level quite acurately. Beginners usually want to solve the biggest of problems, and be done after the next weekend. Mid-levelers usually have specific questions about a method that must be the one true best solution in their eyes, but somehow they struggle with topic X. High skilled people usually ask questions that can't be googled, and even other experts need to look into the problem more deeply to figure it out together.
It's also hard to fake, since you need have some experience in the area to recognize how your current believe is limited. You cannot ask a ungoogleble question if you don't know already most of what can be googled about that topic.
Sometimes the best question is the simplest one. I agree the original has a lot of scope of improvements but I prefer the debate and the range of answers which wouldn't have been the case if the original question was more specific.
