Question: If someone asks a question in Chinese, is the whole post "fair game" for feedback?
A hypothetical example:
But answers comment on the grammar in the first part "我问我朋友这个问题，但是他们不知道", perhaps in addition to answering the main question. [I think it needs a 了, i.e., 我问了...]
There's a related post at CodeReview.SE: Is it okay to give a review without actually answering some of the OP's requests?
And their on-topic page says:
...any aspect of the code posted is fair game for feedback and criticism.
But the situation is slightly different here, since the question encompasses the whole question.
(I haven't gone through each language site to see what they do.)
