I always thought that a story has to be understandable even if you only have the text. Sure, us fans read interviews and blogs and listen to commentary, but what about all the fans that don't do that?
IMO whatever the writers want to communicate they have to put into the text itself. They can't just expect people to be informed about all the secondary information.
