Santtu: you're Finnish, right? I'm half Finnish and I think I've ended a few. I would suggest it as a Finnish/Northern European thing, but that would leave out FDG in Southern Europe. Perhaps it is just European (ok, I'm basically Canadian but I fancy myself European.)
Heyyy! I'm Canadian who's a quarter Finnish!
Maybe I'm just the right amount of not-Finnish because I don't feel like I have this thread-ending skill.
