Facebook is one of the most widely used social media sites today. It connects people around the world with old friends, new friends, classmates and relatives. MySpace served somewhat of the same purpose a few years ago but its popularity eventually died out, especially when Facebook gained popularity.
Gov. Jay Nixon signed legislation on Friday repealing a contentious law that had limited online chats between teachers and students and had caused a judge to warn that it infringed on free-speech rights. The law, enacted this year, barred Missouri teachers from using Web sites that allow "exclusive access" with students or former pupils who are 18 or younger.
