Studying similar (faq-proposed) question at SO Meta and especially its accepted answer helped me to make my mind on that:
Above brought peace and light into my life.
Now, if I can imagine an answer making good tag wiki, it means question is OK to me. assuming it is on-topic
Otherwise, I take a deeper look into the question and try to find out if there's something wrong with it.
As for the question you referred to, well, it doesn't look OK to me.
While casting close vote I have been choosing between not constructive and too localized.
Per re-reading Q&A is Hard, Let’s Go Shopping! I was rather inclined to vote for too localized but the statement "Which development tool is widely used now?" made me feel that not constructive would be a better match.
Understanding scope of the question helps to find out if it's appropriate or not. "I am a newbie, how do I get started writing new programming language?"
FAQ discourages questions that are too wide:
Your questions should be reasonably scoped. If you can imagine an entire book that answers your question, you’re asking too much.
I think that not constructive close reasons description matches above with "this question will likely solicit... extended discussion".
Not a real question can also match in blatant cases, with "overly broad" close reason. "Need help getting started with programming."
