Lately I had a case that one of my questions was marked "as an exact duplicate".
But what the idea of "exactness" means regarding to questions? The subjects of both questions were evidently different, and even if they were really set in similar context, the two additional steps were required to go from one solution to the other - what was admitted by one of advocates for duplicativness.
Maybe the number of steps would be a good metrics for measuring distance between questions?
How can be measured distance between two questions in any other way?
