It is understandable that if a question has negative rating and is not according to the Q&A format gets reported and closed.

But I've noticed that sometimes there are questions that are also not compatible according to the Q&A format but nevertheless get very good rating (upvotes) and good response, they even have many visits, don't have any flags or reports, and yet they are closed again just because they are not compatible with the Q&A format.

[This][1] is an example of such question. As you can notice it is even favorited by some. I've seen many more similar like this one.

So my question is **Why close these questions when it is obvious that they do provide some sort of help to other users?**

Just as an example, it can be like some sort of exception to the Q&A, that if the question has more then, lets say +5 upvotes, +100 visitors, 3-4 answers and an accepted answer, etc. etc. then it shouldn't be closed just because it is obvious that it is a useful question.
