The Feed as a Constantly Tuned System
Launch library · evergreen read
A feed is never a finished, static product, it is continuously adjusted through small experiments platforms run to see how changes affect viewer behaviour, meaning the exact rules governing distribution shift gradually even without any public announcement. Most of these adjustments happen quietly, with no announcement ever reaching the people actually using the platform.
These adjustments are rarely dramatic on their own, small weighting changes to particular signals, tweaks to how quickly new content gets tested, but they accumulate over time into feeds that can feel noticeably different from how they behaved a year earlier. Individually each change looks minor, yet together they can reshape what kind of content tends to succeed.
This constant tuning is part of why advice about what works on a given platform tends to age quickly, since the underlying system being described is rarely the exact same system by the time that advice gets widely shared and repeated. Treating any single explanation of how a feed works as permanent is usually a mistake worth avoiding.
