EDIT
This is as much a response to another answer to this question as an answer to the question itself. The question itself is JUST FINE! The person who asked the question is JUST FINE too! Any belligerence or subtle inflections of irritability are directed, though diffusely, toward unnamed OTHERS, not toward the individual who asked the question. We are FRIENDLY and well-disposed toward those who make sincere inquiries such as this one... if I may presume to speak with authority not explicitly granted by the voice of the hive collective, which has not, in point of fact, granted any such authority to me.
There isn't any way to respond in the comments, so I'm making my entry an answer.
First, regarding Stack Exchange sites as repositories of knowledge versus active Q&A venues:
- Do not allege that EL&U is uniquely aberrant in this regard. The same question is discussed, repeatedly, on Stack Overflow, Programming Meta SE, Math Meta SE, even Meta SO, about all the Stack Exchange sites.
Next, about the purpose of the site:
There are a lot of Stack Exchange sites. There is a proposal for a new one, English Language and Learning SE, in progress on the SE "incubator" site, Area 51 SE. That may or may not work out i.e. receive enough interest move forward, or then survive public beta. Even if it is successful, there may be a middle ground between EL&U and ELL that is not covered, as someone in the comment thread mentioned. That is okay, in either case.
Why is it okay?
- Because SE can't cover every possible use case with an active forum of users and question answer-er's. It is already quite diverse here, particularly in nuances of English language usage. There is Writers SE. There WAS Literature SE. There is Linguistics SE and Academics SE. There may be ELL SE, and of course there is EL&U SE. All are not exclusive to the English language, but all do provide some amount of coverage to aspects of it. There will be questions for which no SE site is appropriate. I think that needs to be accepted, without rancor, nor a sense of having failed any user.
