Twitter opens applications for twttr, its beta program focused on conversations with rounded, indented, and color-coded replies, hidden engagement icons, more
and we'd love to know what you think. Sign up to be one of the first to try out our new prototype app, twttr. #LetsHaveAConvo Lisa Ding / @lolding : This prototype is our first stab at rethinking the conversational experience on Twitter. By using an indentation structure and reducing visual noise on replies, we are hoping to see whether people have an easier time following and participating in conversations. http://twitter.com/... Mike Monteiro / @monteiro : You don't need new features, you need less Nazis. http://twitter.com/... @jack : just setting up our twttr https://twitter.com/...
Context & Ripple Effects
Twitter had been telegraphing this for weeks: an Engadget report in early January flagged a limited program for testing conversational features with followers, and TechCrunch's deeper look at the upcoming beta app detailed the color-coded, algorithmically sorted replies and hidden engagement icons now central to the design. Opening applications turns that preview into a real funnel — prototype lead Lisa Ding frames it as a first attempt at rethinking the conversational experience via indentation and reduced visual noise.
The reception was immediate and pointed: designer Mike Monteiro's public reply — that Twitter needs fewer Nazis, not new features — set up the tension that will follow the program, between interface fixes and moderation. The bet Twitter is making is that conversation readability, not just content policy, drives whether threads are usable at all.
First-order effects
- A limited cohort of applicants gets hands-on access to the redesigned conversational UI before anyone else, giving Twitter's design team direct behavioral feedback on indentation, color-coding, and stripped-down engagement icons while the main app stays unchanged.
Second-order effects
- If the prototype validates the design, the changes escape the sandbox: Twitter subsequently confirmed it was testing twttr's threaded-conversation features on Twitter.com ahead of an official rollout, meaning the main product absorbs whatever the beta proves.
Third-order effects
- The pattern points to a standing two-track product pipeline — a separate prototype app feeding the flagship — and by May 2020 Twitter shipped a new reply layout using lines and indentations directly out of twttr testing, suggesting conversation-structure redesigns become a recurring release category rather than a one-off experiment.
The trend: Twitter is institutionalizing a dedicated prototype app as its R&D channel, letting conversational-UI experiments mature in isolation before reshaping the flagship product.
