When it comes to posting stuff on blogs, it’s a little safer because the viewers may be random (most of them) or some of your close friends.
However, it is slightly more riskier when you post notes, blogs or status updates on social network pages such as facebook because people can just simply put you down in front all of your contacts. And what would be sucky is that the person who comment to your writings, is your best friend.
The person may not mean any harm, but truthfully it’s kind of a public humiliation.. no?
