In the past, when we closed a question as a duplicate of another, it had to be:
- An exact duplicate, in the sense that it should be nearly identical to the original question, and
- Only the question (and not the answers) were generally evaluated for duplicity.
The new duplicate banner looks like this (example):
This question already has an answer here:
How can i put regex.matches into an array? 1 answer
and the new close banner says:
marked as duplicate by Joseph Silber, Robert Harvey♦ 1 min ago
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
Does that mean that:
We should no longer evaluate questions themselves for duplication, but instead look for suitable answers to the duplicate question, and
Duplicate questions have to have actionable answers to be considered real duplicates, and
Duplicates no longer have to be exact, in the 95% sense?
Given the presence of the "Ask a New Question" link, should users immediately ask a new question, instead of editing and trying to get their duplicate reopened?
In The Wikipedia of Long Tail Programming Questions, it says:
If you’re going to close a user’s question as a duplicate, it has to be a real duplicate. For example, if a user asks, “What does the IP address 22.214.171.124/24 mean?” it’s OK to close that as a duplicate of a more general question like “What do IP addresses of the form a.b.c.d/e mean?” But it’s not OK to close it as a duplicate of a twenty-seven page guide to netmasks. That’s the moral equivalent of saying “RTFM.”
Does that still apply?
