You don't HAVE to post on facebook. I go for months and months and months without making a status update sometimes. But it's a good way for me to keep track of my Canada people right now while I am in Scotland, so I like it :P However I grew attached during University when I used it to procrastinate. And I got so used to facebook stalking and knowing what is going on in people's lives even if I haven't talked to them that now I need it haha. It's evil. But it doesn't have to be STRESSFUL evil! Just boredom-killing evil.
