Kids and the Internet: Please Respond

I was paging through some magazines yesterday and I came across two separate references to negative affects of the internet on children.  The first asserted that too many "gadgets" in the classroom have led to kids not having any manners; the second, from a teacher, claimed that because of internet and TV, children don't get enough practice in resolving their own conflicts and end up tattling to the teacher.

Now hold on just a minute.  I'll be the first to stand up and say that the prospect of raising children in a time of such rapid technological change is terrifying.  We don't yet know all the effects that growing up with internet and TV may have; we can be fairly certain that increased obesity is one of them.  But that's not my point here.  You can't just hop on the technology-blaming bandwagon to explain away childish behaviors.
