Both my 17 y/o and 15 y/o daughters have cells because I want them to be able to get ahold of me if something comes up or I'm running late picking them up or something. Amazingly enough, that's what they use them for and little else. Neither one of them has ever used over ten minutes in a month and most of those are them calling home or making arrangements with friends for school projects. But they are geeky homebodies like their parents.
After some of the stuff I've heard happening, I'm not doing texting/data on the kids' phones. I've heard horror stories about girls sending nudie pics to boys they were crushing on and then the boy would get in trouble and be considered a sex offender for possessing child porn.
That's enough to scare the stuffing out of me.
I've also had, get a load of this, the school send home forms for me to allow my kids names and photos to appear on their websites, etc.
Now maybe it wouldn't be a big deal for a lot of families, but we are the only family with our last name in this city of 55,000 people. It would not be hard to find my kids if you knew what their names were and where they went to school. It's like their running a pedophile catalog or something.
Each time I got one of those forms, I told them they could use my child's name *or* their photos but not both. I think they thought I was as crazy as I think they are, but I haven't gotten any forms like that lately. Maybe fear of liability finally knocked some sense into them.
As far as facebook goes, my oldest daughter has an account and I am her friend so I can see what she's got going on. She's always been one of those no-nonsense, doesn't suffer fools gladly people and she's very nearly her own legal responsibility.
My younger daughter is more of a tender-hearted, optimistic soul, so I am going to have to be a bit more vigilant with her, I think.
My boys are 13 and 11, but mildly autistic and couldn't care less about the internet for anything besides World of Warcraft, cheat codes, and Youtube at this point -- oh, and BYC. My youngest son loves this site, but only for gathering information, not interacting.
FWIW, we don't put computers in bedrooms. We have four computers and they are all in public areas in the house. It's just a no-effort, albeit far from fool-proof, safety measure.
