I have two probably contradictory views on this. First, putting in place no privacy settings makes it different than a diary on the couch; it’s more like leaving a diary on a bench at school. If it’s ok for your worst enemy to look at (for instance) I would assume it’s ok for your parents. On the other hand, I generally take a “need to know” attitude toward my son’s online presence (younger kids don’t have an online presence). He understands that as long as we’re paying for it (and especially since it’s under our name) we have access to his computer, phone, etc. So far, though, I haven’t felt the need to snoop. His sister has, though, which is interesting.
