I'm seeing a lot of great famous Stack Overflow questions asked again here on Programmers.
Why allowing to duplicate those greatest hits questions?
Here are some examples :
What's your favourite quote about programming?
Will you delete or close or merge them?
My 0.02c approach:
1. Temporarily close them as Duplicate on Programmers
2. When Programmers will be out of the Beta, import\merge them.
3. Reopen them
Probably I feel it as a problem because I read and loved hundreds of top voted questions of Stack Overflow and now, seeing them popping up again, it's like a Dejavù.
