Just as Facebook strengthens connections between peers, it can also enhance bonds between family members by allowing them to stay updated on each other's lives and maintain contact easily.

Some "friends" you keep around because you want to see what they're up to, others you want to keep in regular contact with and the rest you're just too lazy to "unfriend." (Why do they make that so hard to do?)
