Actually, back in 2004 when I registered I was living in Paris, so then it was kind of logical to put both in. Never changed it though, when I moved back about year later.
I have relatives there too, so I kind of feel at least partially entitled to things French. (Same with Scotland.)
And then, on Anglo-boards like this one, especially the history sections, it's kind of a gimmick to try to present the French point of view in discussions.
Je me débrouille, plus ou moins, en Français mais ne suis pas vraiment capable à écrire cette langue.
