what's on your mind "On Facebook"

Sometimes I don't get why people post every single thing on their facebook status. Even if it says type 'whats on your mind', you dont have to type every single thing.I am currently eating so and so, I am doing this, i did this,I'm sad, happy, angry, I did that, i am going to do this, i am going to do that, and what not, I think that this think it's so stupid and I don't know how people do this. You can't avoid seeing them cause everytime you login to facebook, it appears on your homepage. You know how frustrating it is to see them especially applications which tells you how lucky/unlucky you are, how do you feel today, psychic predictions and endless quizzes. Is it really true in the first place? Sheesh. Not that I'm complaining bout all status, only some misused ones. They are still status which are meant to be status...What You Think??
