When it comes to our kids, there are positives to this new age digital world! I mean, when my eldest was a young boy he 'played out' and I had many worrying times! he'd come home beaten black and blue after fighting in the park! or on the odd occasion wouldn't come home!
My youngest is a total IT wizard! he has remarkable IT skills! As he's partially sighted he spends a lot more time at home than his brother ever did, but he has the world at his fingertips! He plays x-box live and is having tons of fun with thousands of other kids worldwide, without even leaving his room!
which is good for me..far less worry!
But, we all know the dangers of the net!
I'm fortunate that my Son is very mature, understands all about the dangers and doesn't put himself at risk (he's neither timid nor naive)
I do wonder though, as you say, if it continues to get bigger, what problems it may cause in the future?
