An article on the Forbes website says that Facebook, the largest social networking tool in the world, is dominated by women.

Using data from a number of recent surveys and advertising tools, the report says that the 400-million member site is 57% female and attracts 46 million more female visitors than male visitors each month. Women are more active on Facebook, having 8% more friends and participating in 62% of the sharing activity. Women are also seen as the majority of users on many of the other large social networking sites, such as Twitter, MySpace and Flickr. In contrast, men are most active on sites like Digg, YouTube and LinkedIn, which are more content-oriented and promotional than discussion-based.

The article explains how data shows that women don't just visit different sites from men, they also use social media differently than men. While women often use online social networking tools to make connections and share items from their personal lives, men use them as means to gather information and increase their status.
