Yes, I realize the logic errors and contradictions of that statement. There's enough information posted here to get my full name, the general area where I live, what I do, where I go to church, and by extension my religious and political leanings. Phil Zimmerman would be howling.

In reality the 'net can be a hazardous place. I just watched a special on ABC Nightline about kids posting way too much information to their web pages on www.myspace.com. Three teenage girls were interviewed and all of them had become acquainted with an adult (a police officer) posing as a teenage boy. He had gathered enough information on them to find out where they lived etc. The kids thought they had been protecting themselves and had no idea they had divulged so much. This is scary stuff and very real. My best suggestion: when your kids are that age put the family computer in a common area and know what's going on.

Recently I installed an open source web content filter, DansGuardian, and so far I am very happy with it. I've got it running using squid caching web proxy on a CentOS 5.0 linux server. Total cost to me: $0.00. I'm fairly certain that I'll be donating some money to DansGuardian some time soon. It's that good.
