carl I agree. News is a touchy subject. Everybody has their own opinions and when you set defaults inevitably someone is going to have an issue with at some point them no matter what they are.
I also agree that original reporting should be favoured as long as it is factual but I don't think neutrality is completely in the eye of the beholder though. No source is completely neutral but some sources are clearly less neutral than others.
The question is why does there have to be a source specifically from mainland China? There isn't a Russian source (RT) on the list nor are their any other countries such as India, Turkey, France etc. all of which have English language news orgs. I think it makes sense to stick to the large international wires that you already have (AP, NPR, Aljazeera) and add Reuters because it is also a wire source often used by other papers and leave it at that. The user can always add their own if they want.
