Twitter says it's replacing the Moments tab with an Explore tab, which emphasizes trending topics
Content advisory — Twitter's central Moments tab, which once terrorized obsessive-compulsive users with a blue dot that never went away, is going away.
Context & Ripple Effects
Moments arrived in October 2015 as Project Lightning, Twitter's bet on human-curated event pages bundling tweets, videos, and images across every platform. The experiment never stuck: by October 2016 the company was already testing an Explore tab in Moments' place on mobile, and this announcement makes that test permanent.
The swap also fits a longer pattern of tab churn — Twitter had already retired Discover and Activity on mobile in 2015 and folded Trends into search, so Moments becomes the second curated-discovery surface killed within two years.
First-order effects
- Mobile users lose the Moments tab and its persistent blue-dot notification, gaining instead an Explore surface built around trending topics, news, and search.
- Twitter's curation effort shifts from hand-built event pages toward surfacing whatever is trending in real time.
Second-order effects
- Publishers and brands that chased Moments placement lose a promotional slot, pushing them back toward chasing Trends visibility instead.
- The backlash was immediate among some commentators — one critic argued days later that Twitter should instead highlight best tweets à la "While You Were Away" and called the new tab a mistake, signaling user-experience friction Twitter would have to absorb.
Third-order effects
- The retirement path continued: by late 2018 Twitter removed the ability to create Moments from its mobile apps entirely, making it desktop-only — evidence that curated-event products were being wound down, not retooled.
- If the pattern holds, Twitter's discovery real estate consolidates around algorithmic and trend-driven surfaces, with editorially packaged features treated as experiments to be cut when engagement doesn't justify them.
The trend: Twitter keeps collapsing its curated discovery surfaces — Discover, then Moments — into a single trend-and-search-driven Explore layer.
