Like a lot of academics, I'm way more narrowly specialized than is really convenient. So a lot of the questions I'd be inclined to ask here would be of the form "Can anyone point me to research on X question from Y perspective?" — where Y is some subfield within linguistics that I'm not terribly familiar with. Is this a legitimate use of the site?
I think it is acceptable as long as the scope is specific and unambiguous enough. Keep in mind we decided to discourage open ended questions.
