Meta launches direct messaging for Threads users aged 18 and older, without E2EE support, and announces a “highlighter” feature, starting for trending topics
how do I limit who can DM me? Why does Meta possibly think the only reaction I may have to getting DMs is to turn on notifications when I don't have notifications on for threads in the first place? — Whether you like DMs or not, it's a guaranteed hellscape without providing simple controls over who can even DM me in the first place. … Robb Dunewood / @robbdunewood : The ability to DM is the feature on Threads I wanted the most, however, I do realize that quite a large number of people detest DMs. I think Meta missed an opportunity by not allowing users to disable the feature. . Parker Ortolani / @parkerortolani : Threads is rapidly just becoming Facebook Adam Mosseri / @mosseri : We want Threads to be the best place to share perspectives. As we close out year two we're rolling out DMs and adding a new design treatment that highlights the unique ideas and trending conversations. More to come.
Context & Ripple Effects
Threads has been adding tools to make public conversation easier to navigate, including interest-based profile prompts that route users into active topic discussions. Direct messaging extends that engagement path from discovery into private follow-up.
The move also addresses a longstanding product-positioning challenge: related coverage described Threads’ difficulty attracting influencers amid an unclear user purpose. The new highlighter feature similarly gives Meta a way to surface distinctive contributions around trending topics.
First-order effects
- Adult Threads users gain native direct messaging, but conversations launch without end-to-end encryption; users seeking encrypted private exchanges do not get that protection in this rollout.
- Meta adds a private interaction layer to Threads while using highlighter placement to steer attention toward selected ideas and conversations in trending topics.
Second-order effects
- Messaging can make Threads interactions more persistent after a public exchange, but limited privacy and sender-control expectations may constrain adoption or increase pressure for clearer inbox controls.
- Creators and active participants gain another route to turn visibility in highlighted discussions into one-to-one relationships, strengthening the value of topic-based discovery features.
Third-order effects
- If Meta continues pairing public discovery with private follow-up, Threads could evolve from a primarily broadcast-oriented text feed into a more complete social network; user trust will depend on how safety, controls, and privacy protections develop.
- The rollout reinforces a broader platform trade-off: expanding communication surfaces can deepen engagement, while product choices around encryption and message access become a differentiator rather than a background setting.
The trend: Social platforms are increasingly connecting topic discovery, algorithmic attention, and private messaging to convert public engagement into durable user relationships.
