There was something similiar to what you're suggesting a while ago. Graal News - Used to write articles about servers, give reviews, ect. Not really sure what happened to it though. Also used to have specific journalists from each playerworld, the classic worlds atleast, I remember being journalist for Babylon. I guess it died off however?
Its a good idea in theory but if you are picking people that actually choose to play those servers regularly there is still going to be pro-bias for the servers much like the main news. Good luck if you try it though.
