Be Discreet

• Think twice before you post that risque photo or that off-color comment on your Facebook wall or on a friend's wall. You could easily experience far more exposure than you bargained for, even if you have your Facebook account privacy settings "locked down." Everything you post has the potential for exposure to everyone on Facebook, or even everyone on the Internet if your friends choose to share your posts on their own walls, in email or in another format. This is especially true for posts you place on your friends' Facebook walls. You have no control over your friends' privacy settings.
  
  

Avoid One-Way Conversations

• Back-and-forth exchanges are fine on your Facebook wall -- within limits. However, posts that seem to belong to one-half of a conversation are confusing to people who aren't in on the conversation. If your friend posts a comment on your wall to which you wish to respond, do so as a response to her comment on your own wall. Don't post an entirely new comment on her wall. Likewise, if your friend posts something on her wall that you wish to comment about, do so on her wall rather than starting a thread on your wall.
  
  

Be Responsive

• It's only polite to respond to questions posted on your Facebook wall or to comments on your wall or on a friend's wall that imply that a response is requested. If you don't wish to respond publicly to the comment on your wall, state that you are sending the person who made the comment a private message. If you never respond to your friends' posts on their Facebook walls, don't be surprised if no one ever comments on your Facebook wall posts. What goes around comes around.
  
  

Don't Post Too Much

• It isn't necessary for all your Facebook posts to rival the evening news, or only to address significant events in your life. However, your Facebook wall is not an online version of a reality show. Posting every detail in your life is over sharing and you will come to regret it later, if not sooner. Posting too often will put people off -- even causing some people to block your posts and others to "defriend" you.
