When looking at the Linked section of an answer, it's obvious that some questions are referred to significantly more than others. This is a good thing since it keeps the content in one place. Why re-write the same thing 100 times when we can just reference it once (that's how we handle duplicates anyway).
So, to help encourage people using already written posts as references in questions/answers, I suggest a new series of badges:
- Bronze - Linked Question - Question is referenced by 5 other posts
- Silver - Cited Question - Question is referenced by 25 other posts
- Gold - Referenced Question - Question is referenced by 100 other posts
- Bronze - Linked Answer - Answer is directly referenced by 5 other posts
- Silver - Cited Answer - Answer is directly referenced by 25 other posts
- Gold - Referenced Answer - Answer is referenced by 100 other posts
- Bronze - Linker - Reference 25 posts
- Silver - Citation - Reference 100 posts
- Gold - Reference - Reference 1000 posts
The exact numbers would depend on the actual raw data, but something like that to help encourage referencing content...
Now, the answer badges would be much harder to get, since it's usually the question that's referenced and not the answer, but that could be part of the challenge of it.
