I tell parents to think about the 3Cs (content, contact and cost), the 4Ps (privacy, predators, porn and piracy) and now am telling them to think about the 3Gs (gangs, guns and gambling online).
Bottomline, anything that can go wrong in life can go wrong online, sometimes in a magnified way.
Everyone needs to remember what our parents taught us and grandparents taught them. There is a difference between right and wrong. And wrong can look like fun (and sometimes is if you don't consider the consequences and the hurt to others). But we need to remember that staying safer online requires our kids to use the "filter between their ears."
work on it.
