One of the biggest concerns for parents is what their children are doing on the Internet. Who is contacting them? Who are they chatting with? How do they interact with strangers? Kim Komando talks about this regularly.
I came across a site today where you can listen to podcast about Internet safety called Internet Safety Podcast. So far there are only 2, but based on the descriptions (I haven’t listened to them myself), the hosts “begin by talking about safe web surfing and mechanisms for avoid both deliberate and inadvertent access to inappropriate material.”
