Is there any way to find out how many times a question has been cited by other questions? Obviously this can be done because when you look at a question you can see linked questions on the right under the heading "Linked", though what I'm after is a simple count rather than a list of questions.
Presumably I'll have to resort to the data explorer, though even then it isn't clear how the list of linked questions has been built. Some of the linked questions have been closed as duplicates, but others appear to just mention the target question somewhere in the text.
I ask because I'm curious as to how effective the various canonical questions I've posted have been, and one obvious measure of this is how often they have been cited.
