If there's one thing I did correctly bringing up my children, it's to foster their natural curiosity. It's so easy to amplify that curiousity but our society seems to want to quell it at an early age. When a toddler asks a question, do you answer it thoroughly and ask them a leading question ... or do you purposely provide a minimal answer and go back to reading on your iPad?
I suspect that most of this crowd is pre-child, but you can still interact with someone else's kid. And it can be fun. Think of how Randall of xkcd explores topics and lead them on a humorous quest for knowledge. And it's good practice when/if you have kids of your own. Maybe you'll end up with one of these kids: http://bama.ua.edu/~chytrid/Hughes/HHMI.ugst12.html
