The statistics are quite astounding when you look at them, over 600 thousand users are signing up a day which has grown from the 300 thousand that were signing up in the last quarter and if the growth continues it will mean by March next year Facebook may have over 200 million users. Some other facts that Facebook have released mention that an average user has over 100 friends on the social networking site and that around the world over 2.6 billion minutes are spent on the site a day.
Applications are now more popular then ever with over 700 million photos uploaded to the site a month and over 4 million videos shared. As for International usage the facts show that over 70% of Facebook usage is outside of the United States and its good thing that 35 translations are available with more on the way.
