People who write have one thing in them. They are ready to face the world, whether in a good way or bad. They are ready to take criticism for what they write. Anyone who is afraid cannot be a writer.
One needs to become responsible for what one writes. Just because one has courage and is unafraid, doesn't mean that the writer can write whatever she wants. Because the written word is so powerful, because people take it seriously, the writer has to be careful about things she expresses.
Writing for the public is not a personal diary, where one can spill out whatever is on her mind. The public needs to be spared the chaos in an individuals' mind. Otherwise, that chaos would spill into the public arena, which would cause more confusion.
Since the written page is taken so seriously by readers, it comes with a lot of responsibility to the writer. It is a record for posterity, and everything isn't grist for the mill in a future world. Now, with the media explosion because of the internet and social media, people's attention spans have shortened. The writer needs to keep that in mind.
With so much information floating around, in the future, when it would be time for the society to look back, it would be selective, and look at the useful, what would be useful to itself, and discard those that are of no importance.
