Twitter pulled the plug on its experimental twttr application—for now—and shared some of the feedback it received on the new layouts for conversations that it had been testing.The social network revealed the demise of twttr in a Twitter Support tweet Thursday, saying, “If you’re using twttr, switch to the main Twitter app to keep up with what’s happening.” We appreciate the feedback you gave us through this run of our prototype app twttr. For now we’re turning it off so we can work on new tests to improve the conversation experience on Twitter.If you’re using twttr, switch to the main Twitter app to keep up with what’s happening. https://t.co/xq4emx9HeH— Twitter Support (@TwitterSupport) December 3, 2020 Twitter Support followed up with a series of tweets detailing its “learnings” from the testing, including:The new look made conversations harder to read and join: We’re exploring other ways to make this easier. You want more context about who you’re talking to: We’re working to add this. You want more control We’re iterating on our convo settings. Some learnings:*the new look made convos harder to read & join – we’re exploring other ways to make this easier.*you want more context about who you're talking to – we're working to add this.*you want more control – we’re iterating on our convo settings.https://t.co/UzS08x4Jcf— Twitter Comms (@TwitterComms) December 3, 2020 The social network went on to say that people using twttr will lose access to the app “for now,” and it will “explore what’s next for twttr.”Twitter Support tweeted, “When building new features, especially those that are essential to the Twitter experience, we try new things often. Some will ship and others won’t. While testing in the open, your feedback helps us understand what’s working, and what’s not. The conversation on Twitter is unlike anywhere else. We want people to be able to easily participate and connect with their communities in conversations while feeling comfortable and in control. More to come soon.”twttr debuted in February 2019, with Twitter Support tweeting at the time, “We want it to be easier to read, understand and join conversations—and we’d love to know what you think.”The app was made more widely available the following month, and one of the most prominent changes at the time was the absence of engagements—heart, retweet, reply and share—in the main feed, with users having to tap on tweets to access any of those options.Twitter continued to use twttr to test conversation-enhancing options including a new layout for replies that contained lines and indentations.
