A parent’s job

Social-networking Web site Facebook has agreed to work with public officials in 49 states and Washington, D.C., to erect more barriers against sexual predators and cyberbullies. MySpace, the largest such site, reached a similar agreement in January.
Some of the safeguards Facebook plans to implement include sending warning messages to guardians when a child is in danger of giving out personal information to an adult, finding new ways to verify users' ages and identities and reviewing users' profiles when they ask to change their age.
All of these ideas are a step forward, but nothing is foolproof. Protections must be in place on the user end, too.
Parents generally make it their business to know who their children's friends are and how they get along socially at school. Likewise, they should be concerned with how their children comport themselves online and with whom they associate in cyberspace.
