I thought this was interesting enough to warrant a share.
A couple of years ago, Vladan Joler and his brainy friends in Belgrade began investigating the inner workings of one of the world's most powerful corporations.
The team, which includes experts in cyber-forensic analysis and data visualisation, had already looked into what he calls "different forms of invisible infrastructures" behind Serbia's internet service providers.
But Mr Joler and his friends, now working under a project called Share Lab, had their sights set on a bigger target.
"If Facebook were a country, it would be bigger than China," says Mr Joler, whose day job is as a professor at Serbia's Novi Sad University.
He reels off the familiar, but still staggering, numbers: the barely teenage Silicon Valley firm stores some 300 petabytes of data, boasts almost two billion users, and raked in almost $28bn (£22bn) in revenues in 2016 alone.
And yet, Mr Joler argues, we know next to nothing about what goes on under the bonnet - despite the fact that we, as users, are providing most of the fuel - for free.
"All of us, when we are uploading something, when we are tagging people, when we are commenting, we are basically working for Facebook," he says.
