What are the dangers to your kids using unmonitored social media?

Kids have become avid users of social media. Facebook, MySpace, blogs, Twitter and more have become routine parts of the lives of youngsters across the world. So, is there a problem with this? We know that parental supervision is key to protecting kids from drug use. It is therefore reasonable to assume that unmonitored Internet use is dangerous and may lead to cyberbullying, unwanted exposure to pornography, and revealing personal information to predators.
