Facebook is celebrating its 10th anniversary this week. A few numbers about the social networking site that I found amazing:
1.26 billion: Number of people who use Facebook. If the site was a country, it would be the second largest behind only China.
10 billion: Number of messages sent between users every day.
150 billion. Number of photos uploaded to Facebook by September 2013.
1.3 trillion: Number of times the "like" button was pushed between its launch in February 2009 and September 2012.
