One of the most fraught product questions at Meta is: what sections of their apps show up first when users are navigating around? These are some of the world’s most valuable pixels, and any tweak to what shows up in them has a massive opportunity cost. They’re shipping an updated design for Facebook that will customize these based on user behavior. Facebook ran into an odd problem after a while, in that the service is a little too big for a single app, but the sub-services within it, like groups and marketplace, need the traffic from a single centralized app to retain their network effect. So, over time, the app itself will end up getting customized the same way the feed is—and Meta will use that feed to get an up-to-date profile of every user’s narrower interests.
