A recent York University study qualified what we’ve all been thinking - when Facebook activity is up, chances are confidence is down.

According to Soraya Mehdizadeh’s study, the more prolific the Facebook activity, the lower they rated on the Rosenberg Self-Esteem Scale and the higher in the Narcissism Personality Inventory.

Interesting that, as Brian Solis recently blogged, social networking online is converting introverts into digital extroverts.

One could argue when it comes to spewing endless streams of Farmville updates, profile picture changes and status updates, there isn’t much social about that.
