I came across this question today after it had been revived by another answer.
Difference between latch and flip-flop?
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?
