Hugh Pickens writes writes: "CNN reports that a recent study published in the journal "Social Psychological and Personality Science" found that adults have almost as much need for being popular on Facebook as teenagers do and people who crave acceptance are more likely to share personal information says Emily Christofides, lead author of the study. "If you're someone who has your privacy settings set quite high — you don't post your birthday, you don't post what's going on in your life — you're not giving other people the opportunity to comment on those things," says Christofides. "You're going to find that there's less going on on your page, and you may actually feel less popular as a result." The study also found that those with higher self-esteem are more likely to protect their personal information and that some Facebook users have little use for Facebook birthday celebrations and feel overwhelmed by the repetitive flood of "Happy Birthday!" wishes. "The quality of birthday well-wishes means way more to me than the quantity of them, which typically happens on Facebook," says H. Chung So. "Birthday wishes are very well-meaning. But if you get flooded with them, it just dilutes the impact.""
