I first planed to concentrate on accounting-related articles but now I edit whatever I'm interested.
I've lived in Japan, United States, and Germany and have spent enough time to be fluent in the languages spoken in the two former countries. The experiences living with German- and Spanish-speaking families were not long enough so I only understand some of those languages.
I try to input world news from Japanese sources into Current events. By the way, I like to link to whatever articles exist. See oyakodon for example.
