This is a feature request, sorry if this is the wrong form. 

It would be useful for projects such as wikipedia if there were some tool that could take a 
list of two or more users and have the tool spit out an interrelationship table that would 
reflect how much interaction any two users have with each other. This could be accomplished by 
going to each user's contribution list, and then counting the posts made by each user to the 
same page and multiplying them, or adding them, or possibly being able to select different 
algorithms.

If Alice posted 10 edits to an article on chess, and Bob posted 5 edits to that same article, 
in an overlapping period of time, then this would reflect some history between the two 
editors. Threaded replies in the same subsection of a talk page should indicate an involved 
relationship. 

The point of this tool would be for all the various wikipedia polls and voting procedures. 
These polls unfortunately allow someone with a grudge to vote against a good user, or an ally 
to vote in support of a bad user. Some sort of numeric indicator of interrelationship between 
the editors would let people know how much interaction they've had with each other, and may 
indicate some bias. 

ideally, when selecting a jury, all the jurors should not have any prior history with any of 
the parties involved. While creating a jury on wikipedia would be impossible, this would at 
least give some objective measure that says this guy has been working on a lot of the same 
articles as this other user, and may have some baggage coming with his vote. And a user with 
little interaction between any of the users invovled should hopefully be a more neutral voter.

A way to easily display links to the overlapping edits that both users have on the same pages 
would be handy as well.
