i think if i had children i wouldnt let them use myspace. maybe not even facebook. i'd let them however use forums. people dont generally (and i know there is the odd few) but generally, people dont use forums to prey on young children. id feel a lot better if my child used forums, that i could join and keep an eye on.
its impossible to watch everything tho, we dont have eyes on the back of our heads. from the age of 14 i went off meeting people from the internet. infact at 15 i went 200 miles north to a theme park and met up with a bunch of guys from a community i used to be in.
you probably think, young and naive, but i was more street wise then most people my age. tho yes i was in a dangerous position, the gys i met all 2 or 3 years older then me. 6 of them 1 of me. etc etc - but it was a time in my life i didnt care too much what happened to me either way.
good news is those guys were great, became great friends on, and 2 years after that i actually moved the 200 miles to live in the same city as them all.
6 years after that first meeting, we're all great friends still
ive traveled abroad too and met people. and even to this day i still travel everywhere meeting people from the internet.
