Why do people sit in chat rooms so much of a day and night time? Obviously they have nothing better to do. Are they lonely? Antisocial? Lack Social Skills? Lack Confidence? No Friends?
I wish I knew the answer. but sitting in a chair for most of the day is not good for your posture.
For me, I just enter for a short time during my lunch for amusement. It's good to read a variety of messages and attempt to analyse the person behinde the screen.
I don't get involved because this is just a typing medium with no real feelings or meaning.
