American or British English?
It seems like we are not supposed to be using one or the other. I noticed that this is even true for Wikipedia. Within one English Wikipedia article I just read the words "organization" and "organise." I guess for now people will translate using whatever they normally use and the American version will most likely "win" since there are more Americans.
Maybe. Though I do stand by the point that just because enough people do it, doesn't make it right.
On wikipedia, their general rule is that they keep the style of whoever first wrote the article, unless the article is very tied to one particular country. For example, Constitution of the United States would be American English regardless of who started that article.
