There's a dilemma. If the news sources knew what your preferences were, and you'd somehow pay the cost of filtering the news, then they could ship you just what you wanted. No more stories about mishaps across-the-ocean, or on topics that disinterest or rankle you, or from agencies you don't trust or want to support. OTOH, who wants their detailed preferences out in the wild? Clearly a tailored model is better; how can that be implemented, in a way that doesn't filter out what you do want to hear about? Seems like the filtering should happen at the client end. Are there ways to do that? (EG I might temporarily want to follow something for a week. Then not.) But: what's the incentive for the sources to feed your filters?
