Facebook's latest app, Paper, signals two major moves for the world's most popular social media platform: It's doubling down on mobile while continuing its push to become a social news network.
Facebook, in its continuing quest to make its social network more public and "newsy," announced "Trending" on Thursday, a new feature that will put a list of trending topics up in the top right corner of every user's News Feed. The addition of this feature confirms that Facebook sees Twitter as both a threat and a model for news-focused social content.
