That's a great topic and I've wondered it myself. I think I get on here when I have a question about something or when I'm feeling alone. Sometimes I'll get on when I'm bored too just to see what people are saying. I think it has a calming effect on me for the most part. It helps to know people are thinking about the same things I am. A lot of times I just want a connection to people, even if I don't comment on anything it helps to know there are people out there like me.
