Facebook just designs too much to data/metrics, doesn't feel like anyone there really has a vision for what they're building. End of the day without that everything they build will ultimately be soulless because building to the vision is what imparts soul into a product.
So many great products have been hamstrung by designing for the nearest-term metrics available. I don't understand why so many highly intelligent people keep making the same obvious (to the consumer) mistake.
