Editor Interaction Analyzer 

Thanks for your great analyzer, but there seems to be an issue that you might want to check. There is a discussion at WP:ANI where user X claims user Y is hounding them, and Y asked what tool could be used to check what pages they had both edited. I thought I would check that using a couple of tools. I forget why (I might have been wondering about the differences from what I saw in your tool and Intersect Contribs), but I decided to use some local text massaging of the raw data from each user's contribs.

Compared with Interaction Analyzer, my  found 16 extra pages (including 7 extra articles) edited by both users this year (from 2012-01-01). For example, Madurai (history) is not on your list. That might have something to do with the fact, as mentioned by your tool, that one of the users has over 50,000 edits? This is just FYI, no need for a reply.
