This question already has an answer here:
I've recently had two questions closed because they are not constructive or subjective. In both cases I was asking for specific information and while perhaps more than one answer would be valid, they would not be subjective in nature.
For question one Something like libgdx for C++ / cross-platform (with mobile) SDK I'm asking about a very specific comparable technology to an existing library. I'm not asking for opinions about which is best, I'm just looking for them. In this case I find such questions valid because there is no straight forward manner by which they can be found via web searching.
The other question Any common mobile device which doesn't support C++ Exceptions is a targeted question about one particular language and devices on which it may not work. Again, it is not an open ended question and it is not subjective. It is also very difficult to obtain this information via general searching.
Both questions have value to people browsing the site (provided they have answers) which would be difficult to locate elsewhere. Neither of them invite open-ended or chatty discussion, nor are they requests for opinions about technology. The answers in both cases are expected to be limited -- if there were an abundance of answers searching would have revealed it.
Does it make sense to close such issues just because they may appear, at a glance, as subjective questions?
