15 Facts You Didn't Know About Facebook

1. Al Pacino was the first face on Facebook.

It’s actually a young Al Pacino, for reasons unclear. The logo was created by Zuckerberg’s friend and classmate Andrew McCollum.

2. 600,000 hacking attempts are made to Facebook accounts every day.

What do hackers attempt to do once they’re in? Most commonly, they spam the member’s friends in an attempt to sell counterfeit goods.

3. 64% of Facebook users visit the site on a daily basis.

That’s up from 51% in 2010.

4. Facebook is named as a factor in one of three divorces.

The social network was implicated in a third of all divorce filings last year, according to Divorce-Online, a survey by a British legal service. The reason? Social networking is making it way easier to track down former flames and communicate with potential new flings.

5. More than 1 billion people access Facebook on a mobile device on a monthly basis. That’s about 1/7 of the people on planet Earth.

Also, Facebook has more monthly users (1.28 billion) than India has people (1.24 billion).

6. People have been murdered for unfriending someone on Facebook.

In 2012, a Tennessee man fatally shot a couple who had unfriended his 30-year-old daughter on the social network.

7. Facebook tracks which sites you visit, even after you’ve signed out.

In 2014, Facebook told Ad Age  that it will start tracking users across the Internet using its widgets such as the Like button, but that’s only one step in the company’s long History of privacy quicksand.

It’ll probably happen in either the 2060s or the 2130s.

12. Adding /4 to the end of Facebook’s URL will automatically direct you to Mark Zuckerberg’s wall.

There’s more! Adding 5 or 6 to the end of the URL will take you to the respective profiles of Chris Hughes and Dustin Moskovitz, who are Facebook co-founders and Mark’s former college roommates. Adding 7 to the web address takes you to the profile of Arie Hasit, another good friend of Zuckerberg from his days at Harvard.
