I finally gave up on the New York Times as my source of RSS-based news. There are too many articles and despite their length, I never feel like I really learned more. It didn't help that the New York Times US news feed stopped working for me.
I've always preferred the Wall Street Journal's take on the same topic. I still get my business news from the Wall Street Journal, but now I get my US and world news from Google News (US feed, world feed). The advantage is that each feed is capped at 20 posts a day and the news is drawn from many sources.
