I have some etiquette questions. Suppose you read a question that interests you, and you think you could write a helpful answer.
Is it your responsibility to read the answers that have been posted so far first?
If someone has already written a clearly-written answer that is in line with your own thinking, is it kosher to write an answer anyway, perhaps because you think your way of expressing it would be more useful for the OP or somehow better, or because you have more prestige in your paid employment or your publication list (and thus your answer might be more convincing and likely to give the OP peace of mind)?
Should you preface your answer with "I agree with So-and-so, and would like to add my thoughts."
Would it be kosher for the first answer writer to insert in the beginning or end of your post, "I agree with So-and-so, and would like to add my thoughts."
When I am deciding which posts I would like to upvote and downvote, am I supposed to take chronology into account?
I'm not posting a link to an example because I don't want to embarrass anyone.
