I have both a Facebook and Twitter account but very seldom post anything other than "Happy Birthday!" type things. I far more enjoy reading the nonsense and attention-seeking things my friends post about their own lives. I would just feel too weird to post what I'm eating or what really hurt me today etc for all the world to see. I don't understand the appeal but to each his own.
Forums such as this one I am fairly honest and don't feel I say anything I wouldn't be willing to say in real life to people. We all have ours views and opinions. I also have a very good relationship with my employer who knows almost as much about my personal life as my friends so I'm not concerned about that angle of things.
I do agree it's easier to judge a person from what they've said online compared to them actually saying it to you, when you can take in their tone of voice, facial expression and posture etc. Something may sound aggressive or insulting online when in actual fact had they said it to your face you would not feel that way.
