As of Tuesday, according to Mark Zuckerberg, Facebook has hit the two billion mark for monthly active users — i.e. more than a quarter, and nearly a third, of all of humankind uses Facebook every month (with the planet's estimated population now at 7.5 billion).

Ever the optimist in what some see as a quest for worldwide mind control, Zuckerberg writes, "We're making progress connecting the world, and now let's bring the world closer together."

Facebook already hit the staggering metric of having a billion daily active users back in 2015, and it had a billion users overall back in 2012, as NBC Bay Area notes. The marketing company Zephoria reports that Facebook has well over a billion daily active mobile users now, and a total of 1.28 billion daily users overall — and just a mere 83 million fake profiles, give or take!

This means that the social media giant is all the more giant, and has seen 18 percent growth year over year in monthly active users — and 23 percent, year over year, in daily mobile users. This despite media attention that has suggested movement to other platforms like Instagram and Snapchat, whose traffic is still dwarfed by the big FB — and it's pretty clear to most of us that each platform, including Twitter, is good for certain things and bad for others, and we all have our favorites and all use more than one.

A recent episode of the excellent, thinking-persons' tech podcast Note to Self explored the idea that we display or manufacture different versions of ourselves for each social media platform, and it's not that these platforms are forcing us to create and perform these selves, but maybe they've just always been in us, and technology is now allowing us to express them in all their variety. Not everyone is an over-sharer or political debater on Facebook, but some of us have probably always secretly been one of these things, even before Facebook came along. And not all of us are careful curators of the pretty meals and flower arrangements we encounter in daily life, but Instagram arrived to let us become just that. Neither, really, reflects our one true self, if that exists, and they never will.

Here's the NY Times' recent think piece on the social revolution that Facebook has become, and whether Zuckerberg has really wrapped his head around the implications of the power it wields, or the responsibilities that comes with.

Short answer: He hasn't.
