I don't mind the social networking junk too much either; it's detrimental in the short term but everybody I know is getting weary of how pointless it is. I've been reading A. S. Neill's fantastic Summerhill School, where he details the things he learned after 50 years of teaching children, and he argues that letting children play is essential to their growing up properly. Freedom to play eventually leads to kids deciding what they most enjoy doing, and it leads to them being more willing to work within their society. Since reading that, I've wondered if social networks aren't just our modern form of play: useless wastes of time objectively, but people will move on from them and find better things to do.
(I hope. Facebook/the status feed are still only half a decade old. If five more years pass and everybody's still just as hooked, we've got a problem; I think we'll see feed obsession subside, but I could very well be wrong.)
It is really up to the parents. Extreme example, I remember having lunch with my cousins and one of them asked how a microwave worked. The dad, an engineer for IBM, disappeared and returned with a magnetron from his basement workshop. And then told his sons exactly how a microwave works.
The eldest son is now an undergraduate studying physics. He was about ten at the time of the question.
As a lesser example, my sister (who is not a Ph.D. like my cousins' father), loves BrainPop. BrainPop makes science fun without getting into too-many of the nitty-gritty details. Which is enough, when you are just 5.

I'm willing to bet some of your generation did not have the same amount of curiosity and imagination you did when you were younger.
I wonder what we will shape for our kids. I hope its not useless iFart apps and social networking junk.
