I have an idea for a social network for kids 10 and under. Sand, grass, swings, hoops, seesaws, and ball games.<p>Social networks make sense for adults because we're removed from my family, friends, peers by geographic proximity and time .. plus we have too many casual "friends" to network with face to face constantly.<p>Kids? not so much. Kids can make friends within few minutes. Let them play outside, somewhere safe.
