Why was How do you configure a Windows machine for a Linux user? closed as too broad?
I can see that it might appear broad. It is broad. But there's a distinction between broad and too broad — broad questions are fine. In what way is this question too broad?
The question has two comprehensive answers that cover all the essential points (disclaimer: I wrote one of them). That refutes the assertion that there “good answers would be too long for this format”. As for “too many possible answers”, I don't see it: it does require a fair amount of effort to get a good answer¹. (Of course I can imagine any number of bad answers, but that goes for every question.)
So why was this question judged too broad?
If this question is indeed too broad, how could it be re-scoped to cover at least the two top-voted answers?
¹ Unfortunately, say I, as the target audience of that question.
Some people have to work on the stream of incoming questions
Who are these people? Are there people being paid to answer SO questions? (honest question). For me this is the crux; if you 'digest' the stream of incoming questions like that then yeah I can imagine you get annoyed by vague, broad, etc questions... But I think that only a small minority of people actually work like that. I answer questions when I stumble upon one and I know the answer. If not, I just move along... Current moderation practices seem to favor the viewpoint of the 1st group, even though the 2nd is larger.vote to keep answers and and to keep questions open you feel are high quality.
Isn't this the reversed-world? And even if I were to go along with this... You guys close questions before I ever get the chance to vote on them. Remember, I am not continuously refreshing the stream of incoming questions like some of you more active community members do. Also... I have NO problem with question quality. I don't mind the occasional lazy/noob/homework question. I have a problem with overmoderation. Sounds to me like you are saying I have to compete with you guys to 'balance the score'..
