Certain rules should apply to facebook....
Do not put a mean comment directed at someone else as your status. Talk to that person. It is really childish to fight via facebook statuses.
Nothing too riskay for your status. Not only your close friends have to read this, people you barely know on facebook can read it.
Never post anything too personal about your birthing process on facebook. Post you are in labor, great!! But no one really wants to no about centimeters, etc.
No one wants to read about your child's poop on facebook.
Other than the occasional posting of a wedding pic for fun or your anniversary, there is a deadline for how long you can keep that up as your permenant profile pic. I am sure it was a happy day but I hope there have been many other happy days since then.
