Facebook CEO Mark Zuckerberg has revealed that the site hit an astonishing milestone last Monday as one in seven living members of the human species all logged into Facebook at least once on the same day. That's a billion people.
In a message posted on, umm, Facebook of course, Zuck said:
"We just passed an important milestone. For the first time ever, one billion people used Facebook in a single day.
"On Monday, 1 in 7 people on Earth used Facebook to connect with their friends and family.
"When we talk about our financials, we use average numbers, but this is different. This was the first time we reached this milestone, and it's just the beginning of connecting the whole world.
"I'm so proud of our community for the progress we've made. Our community stands for giving every person a voice, for promoting understanding and for including everyone in the opportunities of our modern world.
"A more open and connected world is a better world. It brings stronger relationships with those you love, a stronger economy with more opportunities, and a stronger society that reflects all of our values.
"Thank you for being part of our community and for everything you've done to help us reach this milestone. I’m looking forward to seeing what we accomplish together."
With a billion users affected, this theoretically means that unwanted Farmville invites have blighted more people's lives than the Black Death did in the 17th century.
Perhaps Facebook's near dominance of so many lives is why the company is now having to go and invent artificial intelligence instead?
