FACEBOOK'S DESIGN DIDN'T EVOLVE—IT REGRESSED

Summary from the TLDR Design newsletter

Facebook's interface gradually shifted from a predictable, chronological, user-controlled feed to an algorithm-driven system optimized for engagement over usability. Feature additions like groups, marketplace, and reels fragmented the once-coherent experience, increasing cognitive load without transparent explanation of personalization. This reflects a broader design lesson: products don't fail suddenly but drift through small, individually reasonable decisions that erode clarity and trust over time.
