instead of starting a brand new stack overflow in another language they should think of some way of letting people translate questions & answers and earn karma for that. this way, like wikipedia, you can always go from one language to another for the translation
This is a GREAT idea, one of the best features of wikipedia for the multilingual-ed is you can see the same topic in a different language with single mouse click.
I was thinking the same thing, this would be a great feature.
You could get a few percentage of the karma of the original poster when the question/answer gets upvoted in the language you wrote it (And the original poster would get the karama too).
The karma would have the same value across all languages.
Users should be able to approve translations though
If someone asks a question on the Portuguese then it would be easy for an English and Portuguese speaker to search the English site for the answer and then post to the Portuguese site and earn their karma.
