To get an idea of the social strength of Facebook, suffice to say that the spectacular march against the Revolutionary Armed Forces of Colombia (FARC) of 4 February 2008, attended by a million people in Bogotá and hundreds of thousands in 130 cities worldwide, was called by a group of Colombian students through this distribution channel. Join groups was, in fact, one of the most successful utilities Facebook. A user interested, for example, in ecology, was acceding to emerging groups dedicated to this topic. Immediately on your wall received all the information that this group generated. The group of Democratic candidate for U.S. president, Barack Obama, had in June 2008 with nearly one million members. The site was also the most popular for uploading photos (according to statistics of 2008, more than 14 million a day, a total of 1,700 million).

In December 2007, Forbes magazine, as every year, published the ranking of the 25 most influential Internet. One such network stars was Zuckerberg, chief executive of the site, after selling for 256 million euros, 1.6% of the portal to Microsoft. Three months later, in March 2008, Zuckerberg entered the 1125 ranking of the richest men in the world made by the same magazine. Was ranked 785, but it was the youngest of the 1125 and also the youngest in the history of the publication. To evaluate his fortune, Forbes was based on the estimated value of Facebook (5,000 million), and the fact that the young man was the owner of 30% of the company.

Palo Alto offices of Facebook and occupied four buildings in 2008 and directly employed more than 400 people, the company had received bids from Viacom and Yahoo!, and its annual turnover is estimated at about $ 150 million . His major income came from his contract with Microsoft on advertisements. The site had grown three times faster than its rival MySpace, owned by News Corp, Rupert Murdoch's empire. However, it was not all joy for this young talented computer. Three of his college classmates began a trial against him in a Boston court claiming that Zuckerberg had "seized the idea."

Despite swimming in gold, the "new prince of the Internet", as was dubbed by the specialized site Valleywag, is far from the executive to use. Interested in psychology, in his Facebook profile is defined as a "person who likes to do things." Dress shirts and sneakers, and seems to have no great pretensions: "I have a one bedroom apartment with a mattress on the floor, there live", said not long ago in an interview.
