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.

Bad company culture. You can’t do anything new without explaining how it will have an immediate payoff.
