So Facebook hit a billion users this week. You've heard this by now, obviously, it's been the only story anywhere since Thursday. I'm not going to walk you through the whole announcement because if you've opened literally any tech site since October 4th you already know the number. What I can't stop thinking about instead is one weird little paragraph buried in Zuckerberg's own post about it.
He wrote that if he had to guess, the actual billionth person to join Facebook was probably a girl, around 22, connecting from a mobile phone somewhere in Asia. He even gave her a name. Sarah.
I read that line maybe four times before I believed it was real and not something getting passed around as a joke. The CEO of a company that just crossed a billion users decided the most fitting way to mark the occasion was to invent a fictional 22 year old and give her a name like she's a character in a screenplay he's pitching. Not "our billionth user represents incredible global reach." Just: her name is probably Sarah.
I don't know why this bugs me so much but it does. Maybe it's the strange mix of cold and cute at the same time. A billion is an abstraction nobody can actually picture, so instead of leaning into the number the way every other tech company would (bigger, badder, more infographics), he zoomed all the way down to one made-up person. It's a nice writing trick honestly. I just keep picturing this poor invented Sarah getting cited in blog posts for the next decade like she's a real statistic.
Anyway. A billion is a lot of people no matter how you slice it, and the growth curve on this thing has been absurd since I started this blog back in November of last year. I remember writing something snarky about Facebook's IPO stumbling out of the gate back in the spring, and now six months later they're at a billion monthly actives and the stock has actually started climbing back toward respectable territory. Funny how that works.
The thing that actually matters more than the round number, if you ask me, is how much of that billion is coming in on phones now instead of desktops. Something like six hundred million of those users are mobile at this point, and that's the figure I'd be watching if I ran the company, not the headline total. A billion people logging in once a month to see a birthday reminder isn't the same thing as hundreds of millions of people pulling the app out of their pocket at a bus stop. Mobile is where this whole thing either keeps working or falls apart, and Facebook's mobile ad situation still looks kind of messy from the outside.
Small unrelated complaint while I'm here: my Kindle Paperwhite finally showed up this week (they started shipping October 1st, I'd had mine on order since the announcement back in September), and the new front-lit screen is genuinely great for reading in bed without waking anyone up, but the touch response is laggy enough that I keep accidentally turning two pages instead of one. A hundred and nineteen bucks for the wifi model felt like a fair price until I remembered it still shows ads on the lock screen unless you pay extra to make them go away. Charging me to remove ads from a device I already paid for is one of those things that should bother me more than it does, honestly, because at this point every gadget seems to work that way.
Back to the billion, though. Somewhere out there is an actual person who really was the billionth account created, and it's almost certainly not a 22 year old named Sarah on a phone in Asia. It's probably some guy setting up a fake account to stalk his ex, or a kid making a profile for a class project. The real answer is never as good as the story a company tells about itself. That's most of tech, when you actually look close enough.
