Considering our different definition of duplicates on Code Review (Just because code does the same thing doesn't mean that it is the same code, which doesn't make it a duplicate), does this error message make any sense on Code Review? Should we remove it? Can we remove it?
I personally quite like that "warning", it inspires you to create titles that are more imaginative than "FizzBuzz from a file" - how about "IFSFB - Input File Specified FizzBuzz"
Do something different, something that will stand out.
The alternative will be thousands of questions called: "Singly Linked List", or "FizzBuzz", or "Project Euler #13"
If we allow 2, we allow 200 duplicates.
