Graham Holdings launches Trove news reader

Graham Holdings, the former owner of the Washington Post, on Wednesday launched Trove, a news reader app that aims to build on the company's understanding of how people consume news, giving users stories picked by other people who share their interests.

The app organizes articles by topics users follow and selects articles via a combination of algorithms and a board of experts picked by Trove. If users sign into Facebook or Twitter, the app will highlight topics friends are talking about on those social networks.
