Facebook announced yesterday that they are the world’s largest social network on the planet. Facebook’s founder and CEO Mark Zuckerberg made the announcement claiming that Facebook has now more than 300 million users worldwide. It seems like only yesterday they had a mere 150 million users and that has now doubled in 13 months! Mr. Zuckerberg proudly underlined his social network’s steady growth and also announced that the company itself has now become self-sustaining and cash-flow positive. The top spot remains still undecided since China’s largest social network, QZone has also claimed 300 million users. As most of QZone users would be Chinese that would mean roughly every fourth person in China would be there. Personally I find that hard to believe. The third spot is certain though; it belongs to MySpace with 245 million users. If you enjoyed this post, then make sure you subscribe to my RSS Feed or ReTweet.
