The problem is that this is all a lot harder than just news discovery. I don't just want a news item that is relevant to me; I want a
high quality news item. I also want to reward the news source for its high quality.
Solve that problem and I'll come over and hug you.
At least for me, news items I pursue fall into two categories - news I really ought to know (either on the local or national or international scale), and news that expand my understanding of the world due to the high quality of the presentation (think of the great magazine features, and generally the stuff you can get from places like givemesomethingtoread.com) but are not actually directly "relevant" to me.
It's actually the latter category that is harder to find (and where the fact that there is no good source-agnostic reward model for news sources causes me to feel most bad).
