I like the idea. I'd think it would be useless if it wasn't mandatory though.
my thing is there should be some way to protect kids from stumbling on this while trying to do regular research.
once popular example I remember was that for some time, www.whitehouse.com ( as opposed to www.whitehouse.gov ) was a porn site. I wonder how many kids stumbled into THAT. . .
Yeah, I remember that. Also my 8 year old nephew asked me where to get some space info. I told him try nasa. com and he came back horrified. He'd spelt it nassa or nasser which apparently is German for wet or moist. You can imagine the result...
