I agree with H4rl3quin, I believe the internet is good for some purpaces, but there are some sides of it that is negative, but I have always been able to avoid stupid links from idiot friends and stuff like that. Just don't click at links that your friends give you and or atleast google them first.
Well you may get involved in some bad communities, but if you don't have the strenght to develope your own meaning and sense its no hope for you anyways.
I have teached alot of things from the internet, like better grammar (I still suck) and information about things, but its important to develope a real life aswell. So if my future son is sitting much at the computer i would be ok with it, but once he chooses the virtual world in front of the real world i will be putting my foot down, exactly like my father did to me.
