Users can scroll through the chat regarding a given subject by swiping or clicking from their main feed.
Topic-Focused Timelines
The idea is that they are topic-focused timelines that users may swipe or click on from their main feed to scroll through the conversation around a given subject.
Those who can access it can do so from an in-app prompt, and that prompt will show up for certain people who follow related topics and accounts
Content in customized timelines will be served algorithmically, but there is currently no switching to a reverse chronological feed.
While this is only an analysis of the proposed of the possibilities that custom third-party Timelines might provide to Twitter users
Twitter is excited to learn from this test as it seeks to provide users with new options to engage in the public discussion and more control over the material they want to see on Twitter.
