Being vocal is good. Definitely good if it is online. It is really alright if you are vocal online, saying things about you. As in there is really nothing wrong. Others might want to know more about you and they will read, and if they don't want to, they don't have to. No one asks them to be bothered by what you have to say. They can simply ignore them. However one point to note is not to say anything bad about others. Vocal about yourself is okie, but i don't quite encourage about being vocal about others.

So go on... say.
