Perhaps this is a side effect of it being difficult to measure things like "frustration" or "incoherence" at scale. Any team told to own `wall > ` and optimize for "engagement" is going to want to iterate independently on making the most wall-friendly post system they can think of. And unless this is a highly constrained optimization problem, with a centralized design team having coherence as their* KPI, it's going to be unconstrained free-for-all optimization on a team-by-team basis. A well-managed team-of-teams does not imply a UX-coherent team-of-teams. And maybe Facebook is fine with that. It's a challenge we need to face as technical leaders - where do you spend political capital pushing for a better product?
