As much as I adore the internet, it can be quite intimidating. Since the time my son was very young, I've been participating in public forums. It was a learning process on what to disclose and what not to disclose, even as an adult. I don't like to have pictures of myself up, and with my son, I am reluctant to have current pictures of him on the internet.
Facebook is here to stay...and eventually, my son will have a page of his own. Right now, my husband has a page and my son and I use it. I have the password...son does not. He is only allowed to be on it if I am monitoring him. I feel it is a good way to teach him about what is ok and what is not. We only have friends and family on our 'friend' list, and the privacy is set to max. BUT, some of the older nieces and nephews still put up things that I wouldn't let my son put up. Nothing horrible, just a good chance to show my son that you should be careful about what you put out there for the world to read and see.
He also has an email account (under my business domain). His 'in' box sits on my computer. I see everything he gets before he does. The computer he uses is hooked into the living room TV, which makes me feel more comfortable as well. I want to make sure he is on the internet from a young age so I have lots of time to teach him what is ok and what is not. That way, when he has more access to it when he is older he can make good decisions. I hope anyhow!!!!
