Shy people spend more time surfing on Facebook, but disclose less information, finds a new study.

However, the study shows that even though introverts spend more time, the relationship benefits of Facebook tend to accrue to extroverts, narcissists and people who desire great control over how they present themselves.
Dr. Sheldon's research suggests that the 'rich get richer' hypothesis is at play even on Facebook as the more extroverted a person is, the more status posts he or she is likely to make.
The study also found that women divulge more personal information than men do.
