Sadly with RSS we never got to the point of building networks. People subscribed to the producers directly, but never to brokers. My underlying assumption is than news coorps are brokers in a way, we should not build a network based on them, cause they have a conflict of interest. So everyone ends up maintaining a huge list of feeds, rather than relying on other.
