I came across this question today after it had been revived by another answer.
And noticed the two most recent answers both had comments noting that the question was two years old and that the answers hadn't contributed new information.
I haven't seen this policy in this SE site before (or any other I frequent) and was wondering what the general consensus is.
My understanding is that there is nothing wrong with answering old questions and it is encouraged, but I am unclear on the duplicate information policy. I have seen questions where the same information has been presented, and sometimes it is useful because two answers may explain the same information in different ways and a user may find one helpful and the other not.
What is the general consensus on this?
