Facebook just announced that they host over 10 billion photos now. Over 300,000 images are viewed every second.
Those numbers are simply staggering. It makes you realize just how much of a walled garden Facebook is, since they're so invisible to general users. I see maybe a few hundred photos on Facebook when I log in.
We'll give the always brilliant Nick Carr the final word:
I did a quick scan of the 10 billion photos and found that 3 billion of them included an image of beer, in keg, can, bottle, or pitcher form, 1.5 billion included an image of a bra, and 675 million included both beer and a bra.
