X tweaked its algorithm on July 13, 2026 to increase the visibility of posts from users’ mutual followers, head of product Nikita Bier said. The modification addresses missing data that previously reduced the appearance of mutuals in reply threads, a condition Bier said made the reply section feel like a battleground with unfamiliar participants. The change does not fundamentally alter the user experience but may make the platform feel more community oriented, Bier added, noting it could help interest clusters form more easily, a request from many users. X has introduced several recent changes, including a revised compensation model aimed at encouraging original content and a video editor intended to simplify content creation for users. The algorithm tweak follows comparable moves by Meta’s Threads, which has adjusted its recommendation system to foster community and introduced a user‑controlled feed feature, contributing to 500 million monthly active users. The adjustment does not drastically change the platform’s dynamics, and its long‑term effect remains uncertain.
