What is the psychology of people who have no dynamics in QQ space and circle of friends?

Some people are cold or sensitive. They don't like to bask in their daily life in front of strangers. They only publish updates occasionally to commemorate some special events and share them with friends, so their circle of friends or QQ space is relatively clean. In other words, they don't update often.
