I have a reputation for being a prolific interwiki editor. This is something I'm rather proud of, but gets me a lot of "what the hell is wrong with you?"-type questions, not only from people in real life who I try to explain this to, but also from my fellow Wikimedians (and if they don't get it, the average person doesn't stand a chance).
What most don't understand is that I have a very, very strict philosophy regarding interwikis. Read on to better understand the Way of the Interwiki.
