The main point to be noted here is that we are humans. We are built to express our views, thoughts through different mediums. Where some people write and express their life experiences, some sing and some paint and some through photography express themselves.
It is part of our nature and I think a very big gift from God.
Regardless of what you write, there are people who can tell your personality by just looking at your writing pattern. You can't really hide your thoughts and views. One or the other way, you will speak up and sometimes you will really get amazed that how someone would start talking about you even though he has never met you.
