I recently asked a question about features that people thought were missing in Visual Studio on SO. I tagged my question as subjective when asking, but it was quickly closed as "subjective and argumentative".
I presume that subjective alone is not a reason to close a question. There are many questions out there that are purely subjective from which I personally have gained a lot from reading - world's greatest developer mouse, etc.
I'd be interested to hear opinions at to why this question is judged "argumentative", other than in the positive sense of that word.
Edit: The question is no longer marked as closed, and there is no apparent revision history! Man, is that freaky to you?
