Your Feeling Online

More and more friends are putting writing their feeling on social media. They want to share what is happening with them to their friends by putting it online. What do you think about it? I sometimes don't really understand about that. You're angry with your spouse or girlfriend, and you write and express your feeling there, you write online about your anger and many other things which is not supposed to be expose there. Maybe those people don't really understand the power of the social medias. Will it be good or bad thing for them after all?
