Freedom of Speech or Privacy?

The internet is a thing of my daily life. I use it during and after school to do research and projects, to communicate with family and friends and for entertainment in general. I am one of the billions of people, caught up in the cyber world of the internet. However, when it comes to the issue of publishing and policing on the internet, I find myself caught in the middle.
I think the internet has brought lots of opportunities for everyone. It's provided a place where you can voice your opinion and have people listen. Blogs, Wiki's and even twitter, have made communication ( whether for work or planning a camping trip) faster and more efficient. Relatives, friends and colleagues can talk to each other instantly from all over the world. The net has helped to create a world for middle eastern Women as well. The Bedouin women in Israel are part of an extremely isolated group. The internet allows them to socialize with other women and also boys, something that is otherwise forbidden. In Egypt, Facebook allowed the young generation to socialize and organize. Last spring, a protest was staged using Facebook, against rising food prices. The internet has changed our lives for the better in many ways, but I'm still aware of the problems it has brought too. Internet bullying is a reoccurring issue. Chat rooms, Msn, Facebook and Myspace have revolutionized communication but they have also changed bullying. Now threats, confrontation, comments etc. don't have to be made right to the persons face. The internet has provided a way for bullies to reach there victims anywhere. Now, whether it's after school, over the summer or just a weekend contact is still possible. Also, as much as the internet has given people a voice, it's also created a shield. When you talk to someone online in a chat room or on an online dating website how do you know they are "real"? Is their display picture really of them? Are they lying about what their interests are, where they live, how old they are?
Personally, I think that the positives of the internet outweigh the bad, and that full out policing would take away some of the great opportunities that have been presented by the internet. However, I think that we should all be aware of the risks when using the internet and how to avoid them. My idea of policing, involves teaching kids, teens and adults how to be safe internet users. I think it is a good idea for Parents to "police", be aware and monitor, what their kids are looking at on the internet.
When looking at policing on a larger scale, how do you go about doing that? Who sets up the rules of how the internet will be policed? Who will enforce these rules and how? What will be the punishment for breaking them? These are all questions that make me think world wide policing is a job no one is willing to step up to do. I think awareness and learning are both aspects of policing the internet. Both things help everyone to make smart choices and allow us to recognize when smart choices aren't being made.
