This is a reasonable thought! You can replace a lot of what was great about RSS with various Twitter work--creating lists for your favorite "feeds" (so you'd follow @PopSci instead of subscribing to PopSci's RSS feed) is a surprisingly adequate replacement. That's assuming you're constantly staring at Twitter, which I am, because I am a Cool Dude, but won't be quite for everyone. For news junkies, Twitter is definitely the fastest way to get news--but for more leisurely readers, maybe not. You can use Twitter in conjunction with Instapaper to save articles for later, offline reading--it takes a bit more effort, since you have to monitor Twitter, click a link to a page, and click the bookmarklet that'll sync it with Instapaper--but you're left with a pretty decent way to get to-the-minute news as well as longer, less timely stories. We recommend TweetDeck as the best power-user Twitter client, though it too will soon cease to exist.
