M: Ruth Peters is a child psychologist, hey, Ruth, good morning. Nice to have you back.
W: Good morning, Matt.
M: I look at it like the rules for photos online are a little bit like the rules for wearing a microphone around here. If you don’t want someone to hear it, you don’t say while you are wearing a microphone. If you don’t want someone to see the pictures, don’t put them online.
W: There is absolutely no control once it goes online. I don’t care if it says it’s personal, it’s private, whatever. Once it’s on there, somebody can actually copy it, paste it to their own website or into their own computer. And even if you sanitize that site afterward, those people still have it.
M: And if you are a parent, and you’ve got teenagers, daughters, sons, this Facebook craze, and this MyS-pace craze is part of their daily socialization, how do you convince them that what can seem fun at one moment can become a nightmare another moment.
W: Well, first of all, I think what Miss New Jersey did is probably did more for all of this than anybody could do. And so I think what you do is, you talk to your child, you explain it to them, and then you have to supervise them. That’s the key word; you have to supervise your kids online.
M: I’ll talk about supervising them in just a second but I think a parent has to say to a child, look, this is for your friends and your family. These are the people who are supposed to see these photos. But it only takes one angry friend or one jealous friend to make these things public.
W: Exactly, and that’s where we say you do not have control, and so if you want to send photos to your friends or families, send them an email with that on. It doesn’t have to go into this public sphere.
M: So parents have to familiarize themselves with Facebook and MySpace and all these things. At least they can help their children.
W: And it’s easy, most parents think that the technology is bafflement beyond them, but it’s really very simple to start your own account, to go in, and be able to look and see what your children are doing.
