Is facebook chat as bad as the chat rooms of the 90s? Can kids get into trouble on it? So worried about my grandson.

Yes and no. Facebook can be as bad, but it's more of a sin of commission than before. With facebook, you can filter who knows your information or can post on your page, but once somebody is a friend, they have access to everything, including information about your friends. Children can give too much personal information to people who shouldn't have it. More dangerous as teens don't recognize it.
