500 million people share their lives on Facebook, incredible eh? (see this blog post by Mark Zuckerberg).

For the occasion, Facebook launched Facebook Stories (http://stories.facebook.com/).
“Facebook is all about the individual and collective experiences of you and your friends. It’s filled with hundreds of millions of stories.

On 12th Febraury 2010, I made the following picture: at that time Facebook reached 400 million users and, if it was a country, it would have been the third country in the world. Today, 17th September 2010, it is at 500 millions. Anyway it will take some time before becoming the second largest country in the world, considering India has more than 1 billion citizens.
