People who aren’t emotionally stable post more frequently in order to regulate their emotions and receive social support:Low emotionally stable individuals experience emotions more intensely and have difficulty regulating their emotions on their own.
Consequently, we suggest that they use the microblogging feature on online social networks (e.g., Tweets or Facebook status updates) to help regulate their emotions.
Accordingly, we find that less emotionally stable individuals microblog more frequently and share their emotions more when doing so, a tendency that is not observed offline. Further, such sharing, paired with the potential to receive social support, helps boost their well-being.
It might be a good strategy because, overall, Facebook users do get more emotional support than other people. (Here are some great tips by experts for using Facebook to enhance your happiness.)

Your Facebook “relationship status” says a lot about how happy you probably are. What’s a really good sign? Men who listed their partnership status (“In a relationship with…”) and women whose profile picture displayed their partner both had happier relationships.
In fact, Facebook can predict with a 33% accuracy who you’ll be dating next week:

As the service’s engineers built more and more tools that could uncover such insights, Zuckerberg sometimes amused himself by conducting experiments. For instance, he concluded that by examining friend relationships and communications patterns he could determine with about 33 per cent accuracy who a user was going to be in a relationship with a week from now. To deduce this he studied who was looking which profiles, who your friends were friends with, and who was newly single, among other indicators.
And those people posting all those status updates to regulate their emotions may not be aware of the main reason for un-friending:
Posting too many boring updates.
