Facebook execs flocked to London this week to promote the social-network's first Developer Garage in the UK. While they were there they confirmed just how many people in the UK use Facebook.
The answer: a cool 26 million. Considering the UK population is around 61 million, this means more than a third of the UK whiles away its hours on the site.
In celebration of this number TechRadar, who was at the Developer Conference, has decided to do a bit of number-crunching regarding the biggest social-networking site in the world.
So, for your reading pleasure, here are the numbers which make Facebook tick.
