teens and the internet

I was very moved by what was said on Dateline. Teens today are absorbed by the technological tools available to them. i.e. internet, myspace, facebook, texting. I am very concerned about the repricussions that teens could be facing by their openness on the web. As a parent I am horrified by what is available at the touch of a button. I am more concerned that the young individual that is posting the most private parts of their lives on the internet for everyone to see, has no comprehension of just what they are doing. It's not just their personal friends that are looking at it. It can be anyone. And the information never goes away. If someone wants to find your postings bad enough, they will. That means future family, friends, and employers, even predators. Young people do not have the experience of life to look beyond today and see how it might affect tomorrow.
