Twitter starts testing Reddit-like downvote button on iOS
 

Some Twitter users on iOS might see a new button that looks like Reddit's downvote button in people's replies. That's part of the social network's latest experimental feature designed to give it more insight on what kind of replies users find relevant in a conversation. According to Twitter Support's announcement, the goal is to be able to gather enough data, so the platform can work on ways to surface more relevant responses. In long threads, for instance, the best replies don't always show up immediately and might be buried underneath tons of other people's tweets.
