Consider biology. If someone asks what defines a hedgehog then people will have to list a set of characteristics, a long set actually. When defining a mammal the set of characteristics will be shorter and when defining a living being the set of characteristics will be just one, autopoiesis.
General questions require general answers and general answers are usually shorter and easier to give, for someone knowing the answer or with enough analysis and synthesis capabilities as to abstract from the details of the particular examples, analyse what is common between them and synthesise it in a short general answer.
If some specific person lacks these capabilities, there is nothing to be ashamed, no need to worry, simply let some other guy answer the question.
Why do people keep complaining about some questions being "too general"? Where does the fallacy of general questions being hard or impossible to answer come from? Can we get over it yet?
PD: What about foundations and fundamental questions? Specific questions are anecdotal. The Universal Law of gravitation defines how gravity should behave in the Universe, not for an specific apple falling from an specific tree. I understand that this can be shocking when most questions are asking for a specific data, but more general means more fertile, more useful in a wide range of situations and for more people.
