Here is something that came through my Facebook Newsfeed :
“Adding the number 4 to the end of Facebook’s URL will automatically direct you to Mark Zuckerberg’s wall.
Just in case you’re not familiar with the term “URL” – type this web address: www.facebook.com/4 in your browser. We’re not sure why Zuckerberg chose the fourth ID number instead of number 1, but this is a quick and easy way to get to the original Facebook wall that is owned by its creator.
Adding the numbers 5 or 6 to the end of the URL will take you to the respective profiles of Chris Hughes and Dustin Moskovitz, Facebook co-founders and Mark’s former college roommates. Tacking a 7 onto the web address leads to the profile of Arie Hasit, another good friend of Zuckerberg from his days at Harvard.”
