Noting that breaking news stories move a lot faster through Twitter than aggregation sites like Google/Yahoo News and Digg, a Yahoo BOSS engineer created a news search tool that ranks based on Twitter links. TweetNews keeps an eye on Yahoo News and compares its headlines with which news stories are culling links on Twitter updates. A story’s popularity amongst the tweeting masses will push it up farther on TweetNews. There’s no landing page full of links, though, just search functionality. You can see the Twitter updates each result is pulling from in a drop-down box, and the absolutely minimal site loads seriously fast. TweetNews is free, no sign-up required, and a decent addition to any news-watcher’s arsenal—especially those who like to be really, really up-to-date on what’s happening.
