Like them or not, RSS readers are a very 2008 way to read articles. Twitter has supplanted RSS for many people; I've personally gone from watching hundreds of RSS feeds to watching hundreds of Twitter feeds, and I'm not the only one. Twitter can function like an RSS reader with a bonus social element. An RSS feed is carefully curated and streamlined, but Twitter doesn't work like that--though you can try to make your Twitter stream tight and only follow certain accounts, those accounts can retweet other accounts, or respond, or converse with each other. It's unpredictable, but it gives you a much wider range of sources. You never know what you're going to get, which is philosophically very different from RSS.
