Hmm.. I think it really depends on what you are surfing the web for. I'd say I spend half the time that I'm surfing just reading news and learning, while the other half is just getting entertaining myself.  I used to spend an excessive amount of time on the net, but have gotten much better about it.  If the kid is going to be on the net anyways, how about forcing them to learn something new at least once a day, maybe on howstuffworks, wikipedia, or some other site?  Perhaps they'd start getting interested in things they've learned about, and want to pursue a career or start reading about that subject.  Regardless, the techniques the Chinese are utilizing don't seem to be working well.
