This document discusses how newsfeeds work on social media platforms. Newsfeeds aim to show users relevant and timely updates from accounts they follow. Algorithms determine the order of posts in a person's newsfeed based on various factors including the time of posting, type of content, relationship between the user and account, and engagement with similar past posts. The goal is for newsfeeds to deliver a personalized stream of updates that users will want to engage with.
