That's a lot of money for an app with relatively little lock-in and a $0.70 (maximum) ARPU.
Also, even at $1bn in revenue, this is 16X sales... that's usually the kind of price you'd see for a company that can still grow a lot. When you have 1/12 of the world's population as users, and you're capped at $1 per year per user, there's not a lot of places to grow. Clearly FB valued this based on strategic value to their broader platform.
Why would that be the case? There are always other revenue streams to be explored using the same user base.
I would really like to agree, but given recent valuations that doesn't seem to be the case does it?
