Rosanna Guadagno and colleagues asked over three hundred students about their blogging habits and asked them to complete the now industry-standard Big Five Personality Inventory.

Around 20 per cent of the students blogged, mostly about their personal experiences. Among female students only, those who scored highly on neuroticism (i.e. anxious, insecure characters) were more likely to blog. This is consistent with work on internet usage that also found an association with neurotic personality types, but only among women. The researchers surmised that nervous women may blog to "assuage loneliness or in an attempt to reach out and form social connections with others."

Among both men and women, those who were more open to experience were also more likely to blog - perhaps unsurprisingly given that blogging is a relatively new phenomenon and given that this personality dimension is associated with creativity.
