Facebook is reportedly rolling out its "downvote" button to a wider group of users in the United States. "The feature began appearing on the service's mobile app without a formal company announcement -- and we only found out about it by browsing on our phones," reports Ars Technica. From the report: The feature appears to currently be limited to "public" posts. Should your account be flagged for this week's test, every comment in a thread will include a numeric value and small up- and down-arrows connected to that Number. Upon the first display of this Reddit-like change, the Facebook app will offer guidance: "Support comments that are thoughtful, and demote ones that are uncivil or irrelevant." This is in addition to the site's long-running "emotion" interface, which lets users tap "like" or emoji-styled buttons. These icons and numbers still attach to posts as they've done for years. Now an additional value based on up- and down-votes, appears as well, and these values are separate. Meaning, if you tap the "like" button and down-vote on the same comment, those actions don't cancel each other out. As of press time, these up- and down-vote numbers are not visible if your account is not flagged for the test. We have not yet seen this feature go live on any versions of the Facebook Android app.
