I understand the HN crowd may take issue with this, but the ease at which a child can stumble onto pornography or adult content is really scary. Even with google safe search, etc enabled. Growing up watching television in the US, you couldn't see topless women on public broadcast TV, let alone hardcore pornography.
Yes, sure, I understand the concern of having children be protected from things they aren't ready for... ...but is the government mandating this the best way to go about it? Is this implementation even sound?
*Not necessarily agreeing with the proposed solution here of a mandated approach. Just saying that this may be a situation where government intervention is necessary even if it's just to sponsor public education of options that parents have to protect children.
