Facebook is all set to cross the striking 500 million mark of users associated with it, as soon as next week. The website owner has not proclaimed it as of now.

It has been found that the number of Facebook users has now totaled the number of Windows 7 licenses, the number of posts being sent on Twitter every day and the net population of the US.

Launched in February 2004, the website managed to cross the 250 million user limit, last year.

Now, in order to popularize as well as celebrate, the website developers have come up with the idea of initiating a program on the site called Facebook stories.

The program will see the users sharing their experiences after joining the social network and the changes, which they observed in their lives with the regular access of Facebook.

The program is going to be unveiled next week.

In addition, the number of users of Facebook, who access it via their mobile phones, has risen over 150 million since April.

“As we begin to continue to expand, we're starting to go into geographies where phones are the predominant way you access the web”, said Erick Tseng, Facebook's head of mobile products.
