It's not so much that I use the Web as some kind of giant confessional with "like" buttons, but that I can just relax a bit more and talk about even boring and trivial things about myself. I even find it easier to be curious about others and their own trivialities, which I rarely am in physical space. I can breathe.
Whether positive or negative, news can go "viral" and be repeated may times over without the "permission" or knowledge of the subject of the story. By not taking hold of your own online reputation, you are allowing others to put information into the "court of public opinion" instead of creating your own story.
