X Tweaks Algorithm to Show More Posts From Mutual Followers

X made a small but deliberate change to how it ranks content in reply sections, according to Nikita Bier, the company's head of product.

Bier said Monday the platform is rolling out what he called "a small tweak" to boost the visibility of posts to a user's mutuals, meaning people who follow each other back. Bier said the platform's algorithm had been missing that mutual-follow signal entirely, which meant friends were showing up less often in replies than they should have.

"This resulted in the reply section feeling more like a battleground with people you don't recognize," Bier wrote, a line quoted by both TechCrunch and LatestLY.

What Actually Changed

This isn't a moderation policy change. Nobody's getting banned or having posts removed. It's a ranking adjustment, according to voice.lapaas. It affects which posts get shown more prominently in a user's feed and replies, not what people are allowed to post in the first place.

Bier also said the change should help interest-based clusters form more easily on the platform, something he said users have been asking for.

Why It Matters for X's Business

X has spent the last several months trying to make itself stickier for creators and everyday users, not just a firehose of viral arguments. TechCrunch noted the platform recently overhauled how it pays creators, shifting incentives toward original content instead of aggregation, and rolled out a new video editor earlier this month.

Making replies feel less hostile fits that pattern. A platform where strangers dogpile every post is a platform people eventually leave. Retention is the key metric, and Bier's team is betting that seeing familiar faces in your replies keeps people scrolling and posting.

The Threads Factor

X isn't operating in a vacuum. Meta's Threads has been chasing the same problem from a different angle. TechCrunch reported Threads rolled out a feature called "Your Algo" last month, letting users privately control what shows up in their feed, and that Threads has since crossed 500 million monthly active users.

That's real competitive pressure. Threads has positioned itself explicitly as the calmer alternative to X's often combative culture, and it's working well enough that X apparently felt the need to answer.

The Skeptics Have a Point

Not everyone supports this change. According to Digg, which tracked reactions across thousands of X accounts, sentiment on the change was mixed. Supportive users liked seeing more familiar faces in their replies. Critical replies argued the tweak does nothing about the platform's bigger problems: spam accounts, bots, and outright hostility that have nothing to do with whether you follow someone back.

Boosting mutuals in your replies doesn't stop a bot farm from flooding a viral post's comment section, and it doesn't touch the accounts that exist purely to pick fights with strangers. If X's reply sections are a battleground because of coordinated harassment or spam networks, rearranging who shows up first in the algorithm is a cosmetic fix at best.

Bier and X haven't claimed otherwise. He described it explicitly as "a small tweak," not a platform overhaul. The company isn't promising this ends toxicity on X, and it shouldn't be read as more than what it is.

The Broader Pattern

voice.lapaas framed the update as part of an industry-wide shift where platforms are increasingly weighing conversation quality, not just raw engagement, as a retention metric. Engagement-maximizing algorithms have taken plenty of blame over the years for amplifying outrage because outrage keeps people scrolling. If X is genuinely dialing that back in favor of showing people their actual friends, that's a step in a healthier direction, even if it's a modest one.

Whether it moves the needle depends entirely on execution, something none of the available reporting can verify yet since the rollout only began this week. X has not published data on how much reply visibility for mutuals has actually shifted, and no independent measurement of the change's effect on reply-section tone has been released. The open question is whether a ranking tweak can outrun the spam and bot problem that critics say is the actual source of the "battleground" feeling in the first place.
