Reuters isn't significantly better or worse than anyone else, in the scheme of things, but it's a bad idea to have too much faith in any news outlet, regardless of how sophisticated it may currently make you sound when you brag about how you get all your news from Al Jazeera. (Personally I get all my news from Taiwanese animations.)
