The problem is this: Facebook has become a feedback loop which can and does, despite its best intentions, become a vicious spiral. At Facebook’s scale, behavioral targeting doesn’t just reflect our behavior, it actually influences it. Over time, a service which was supposed to connect humanity is actually partitioning us into fractal disconnected bubbles.
This sums up my thoughts on Facebook. Hence why I quit it. Unless they drop “engagement” as their metric I can’t see how it can be fixed.
