The idea is this. There is a lot going down in the world. People have a lot of things to say, but how can you be assured that you're going to be able to get your opinion out there? Whether or not you get published is largely dependent on editorial preference or space. Also, if the editor is interested in maintaining a balance in his or her paper, you may be rejected because too many other people agree with what you have to say.
There is a lot to talk about in our country. And a lot to fix. I believe the first step is being able to vent out what you are thinking in a place where you will not be censored unless you are discourteous to someone else. I hope that this community will be a place where people can write what they think and discuss those thoughts in a civilized manner with other people.
