I have been an RSS user for the past 20 years. I use it for all sorts of stuff including current news, keeping up with technology, health, classified listings (craigslist), site updates, forums, etc.
I used GoogleReader for a long time (RIP), now I use Feedly which is amazing. I hit the ALL button so I get a firehose of news feeds which are sorted by timestamp, NOT some dumb algorithm choosing when and what I see.
As I tell everyone, whenever a current event happens in the world, I see 20+ different headlines from different sites spinning the same story. This lets me cut through the BS and see the real story about what's happening.
I subscribe to a few hundred RSS feeds including a bunch of random useless ones. But here's a few I picked that might be beneficial - note that some of these sites have multiple rss feeds depending on specific topics - be sure not to subscribe just to the main "top stories" feeds.
ABCNews , InvestorPlace, Associated Press, Ars Technica, The Nation, BBC News, CNN, Fox News, The Hill, LA Times, New York Times, MSNBC, Mother Jones, NBC News, NPR, Newsweek, Politico, Time, Scientific America, Slashdot, Techcrunch, TechRadar, The Atlantic, Boston Globe, The Independant, Motley Fool, Google News Top Stories, USA Today, Vox, Wired, Yahoo News, Cnet, Men's Health, TechRepublic, WallStreetJournal, TheStreet
I'd also love to hear some other news sources I can add to my subscriptions, because I know I'm missing a bunch of good ones
