You can't pick up the telephone and say, 'Connect me with someone else who has a kid with leukemia.'
The great power of the Internet is it allows people who don't know each other... to connect with people with shared interests. The shared interests might be that 'I have a kid with leukemia.' Or, 'I'm a Nazi.' It gives marginalized people more power.
Kids automatically teach each other how to use technology, but they're not going to teach each other about the history of democracy, or the importance of taking their voices into the public sphere to create social change.
When it comes to technology, you're in a position of your children having to teach you. How often do kids have any power or authority? How often do parents come to them and listen to them? But it takes a parent with some courage to admit they don't know and want to learn.
