> The US hasn't been the focus for several years. Africa/India/Asia were far more important than sustaining US numbers.

I figured they were only important to keep of the facade of forever increasing user growth. If North America and Western Europe aren't were the bulk Facebook's revenue is coming from (and where most of its focus in placed), I'd be very surprised.

They are the bulk of its revenue, but my point was that average daily/monthly were already peaked by most counters and growth markets were a higher priority. Why do you think they paid so much for WhatsApp.

I'd guess that 500-700 million people in the world from $50k+ GDP/capita countries are actually a lot more valuable for advertisers than the billions from $5k GDP/capita countries. Africa/India/Asia may indeed be driving growth but not all users are equally valuable to Facebook
