Surprised no one has figured out why they paid so much. 20m dau at the time of acquisition means they had 20m+ user accounts (likely 3x that). All of these people are "socially obligated" to stay connected for some amount of time. How much would your company pay to acquire ~60m customers? That's not including the revenue they were bringing in. I don't dispute they paid too much, but apparently it was worth it to them.
