If we all voted based on whether the author's minute biases (displayed within the question text) happened to fit in with our own, this Stack would be a lot less friendly and useful. Instead, we should vote because a question is well-researched and/or intriguing. When good research happens and the question's interesting,
and there is a side remark which I happen to completely agree with, well, expect a "+1 for X" from me, even though the real reason is
a good question. —
