LinkedIn rewards different signals in 2026. Chris Donnelly brings data-backed insights from analyzing 300,000 posts on what works now.

Elon Musk isn't a fan of X's algorithm, so he's documenting the company's efforts to improve the tech that decides what you see in the "For You" feed.

"No other social media companies do this," Elon Musk said

Instagram has rolled out a fresh feature that allows you to personalise your feed: ‘Your Algorithm.’ Here’s all you need to know.

Social media company X has taken an uncommon step in an industry known for secrecy by publicly releasing the source code behind its recommendation algorithm.

Instagram has introduced ‘Your Algorithm’, an AI-powered feature that gives users direct visibility and control over the recommendations driving their Reels feed.

Earlier on the same day Musk said the algorithm sucked, X head of product Nikita Bier seemed to indicate that he was proud of it, noting that in the six months from July of 2025 to this month, daily engagement time from new users has gone from less than 20 minutes to somewhere in the mid-30s.

X has open sourced its new algorithm, with owner Elon Musk defending it as users responded to the changes with criticism.

Elon Musk says he plans to open-source the X algorithm next week, but he open-sourced Twitter’s algorithm in 2023 and then never updated the GitHub.
