4th February: Facebook

On this date in 2004, Facebook was founded. So here are ten things you might not know about Facebook:

1. 1 in every 13 people on Earth is on Facebook.
2. The man whose face appeared on the 2007 Facebook homepage behind a cloud of binary code is the actor Al Pacino.
3. Facebook’s library contains over 140 billion photos, which is about 100,000 times what the US Library of Congress has, and amounts to 4% of all the photos ever taken.
4. The "Like" button was originally going to be called the "awesome" button.
5. Facebook is predominantly blue because Mark Zuckerberg is colour blind and blue is the colour he can see best.
6. The most "liked" company on Facebook is Coca Cola.
7. The average Facebook user has 130 friends and spends 21 minutes a day on the site.
8. Adding numbers after the Facebook URL takes you to the personal pages of the founders. https://www.facebook.com/4, for example, takes you to Mark Zuckerberg's page. 5 gets you to Chris Hughes, 6 to Dustin Moskovitz and 7 to Arie Hasit.
9. Every 20 minutes, 1,000,000 links are shared; 1,484,000 event invites are posted; 1,851,000 status updates are entered; 1.972 million friend requests are accepted; 2,716,000 photos are uploaded; 2,716,000 messages are sent and 10.2 million comments are posted.
10. Your Facebook page can be translated into 70 different languages, including English (Pirate), in which friends are called "mateys", commenting is called "scrawling a mark" and so on. To try this out, on your page, scroll down to below the pictures of your friends where there is some grey text which will either say something like "select a language" or will display the language you're currently using eg "English (UK)". Click on this to get a full list of available languages, including "English (Pirate)". Follow the same procedure to go back to normal English.
