Isn't it odd that DAUs/MAUs is consistently 66% in every quarter? Is this a property of the typical use patterns of Facebook, or something they estimated for SEC purposes?
EDIT: Also interesting to me that US/NA makes up ~12% of users but ~60% of ad and payment revenue - a sort of downshifted Pareto principle.
Alphabet sees a similar tilt. They got 47% of their revenue from the US in 2017. From what I've read I'd guess they have 200 million to 225m product users in the US market and probably 1.5 billion to 2b outside of it.
