This is incorrect. A lot of times people are still learning about the topic they are asking a question on, so its often a case of they dont know what they dont know and simply do not have the means yet to properly ask the question. Mostly because they do not have a great depth of knowledge on the subject already, hence the question. This is also why questions should not be closed as duplicates; it is perfectly acceptable to ask the same question in a different manner as for someone else may find it useful. Do elementary school teachers not answer a child's question because another child asked it similarly in the past? It's more harmful to click on a dozen links to see them all closed as dups and try to find the one that isnt a dupe that hopefully can help you with the question. Do not blame them for trying to learn, or how they are going about doing it. It's a QA site, not a rewrite the manual on programming languages site.
