I've noticed lately that there are questions on Stack Overflow being closed as "not a real question" which are to an expert in the subject clearly "real questions" -- unambiguous, not rhetorical, not overly broad, on topic, with straightforward answers. But the subject of the question is sufficiently obscure that even a reasonably knowledgable person might not "get" what the question is about.
Two recent examples that come to mind are:
Why doesn't C# support the return of references?
Here we have a question that was voted down to I think -6 before Bill The Lizard was kind enough to resuscitate it; it is an excellent question and went on to be upvoted pretty highly.
An example from today is:
Is there attached property in C# itself?
Again, same thing. The question has been closed as "not real" despite the fact that it is on topic and has an unambiguous answer (namely, "no, but we tried").
(It has since been reopened, though of course it is likely that attention brought to it here was a factor.)
The fact that these are both in a sense "the same" question -- namely "does C# support this obscure feature? If not, why not?" -- is I think not particularly relevant to the more general issue. (*) The more general issue here is that both these questions are quite good questions about a topic so obscure that five smart people agreed that it was "not a real question".
I perceive no particular barrier to getting answers to ordinary, boring questions about common scenarios on this site. I think that there is huge value in this site's capability to provide answers to the difficult, obscure, interesting questions. Closing questions about obscure topics early, before experts can actually see them, seems to be working against that value.
Is this more general issue a widespread problem that anyone cares about?
If it is, are the existing mechanisms (voting to reopen, calling in a moderator, asking questions like this on meta, and so on) sufficient to address it?
If they are not, what mechanisms could be improved to address it?
(*) I tend to push back on questions of this form because the answers to them are typically all the same, namely "nice idea but we have higher priorities". These two are exceptions to that rule in that they are both features that we thought were good enough that we actually implemented them before we cut them.
