Nathan, I don't object at all to any wikiconference. I just miss the point of having North Americans present their projects away from the international crowd, to only their fellow-north americans. If there is something very particular that makes these talks unsuitable for people from other continents, I'd really like to understand that better.
Like I said, I'm not aware of any such track or preconference in other countries, with a few exceptions where language played a major role (I think there was a Spanish track in both Buenos Aires and Mexico, and a Hebrew (education?) track in Haifa). Also in an Asian context I'd have a hard time imagining why you would make that so specific to that region - except if it is really tied to language.
Best,
Lodewijk
