In my own experience, Facebook acts more like a multilevel marketing scheme. My circle of 150 friends and not posting on FB near as much as a year ago. It get old. Maybe globally they can make it last a while. Valuing these guys is not my area of expertise. But, it does seem way too high to me. But I hear that 40% of the worlds population does not wear shoes. After shoes they get computes and go on Facebook, lol. As I said, not my area.
