This why gengis doesn't use Facebook.
This one is so true though, I have to admit. You post some important real life stuff and nobody cares, you post something useless and everybody likes it lol.
I have to admit majority of my facebook consists of Ex colleagues + 1 current colleague. However I also have old friends on it from Holland to stay in touch with them, I have my family on it and my ex wife to stay in touch and share pictures of our daughter. It's perfect for those type of things.
Also you can set that nobody can tag you without your approval.
