Facebook is a social networking site. The level of safety is dependent on the user. Keep in mind millions of people have access to the site and with that being said, never give out personal information such as address, phone numbers or other information someone could use to either steal your identity or do you bodily harm. You know who your friends are and if they are your friends that have that information anyway. Face book can be fun and a nice way to make friend as long as you are careful. If there is a person who you feel uncomfortable with on the site, you can block them and he or she will no longer have access to your page.
