Communication is a tool

Communication is basically a tool for us. We use it to fullfill our needs like getting noticed, and getting information and passing it to others.

In this sense mediated communication is just a technologically powered tool. We can do more good or bad with a powerful tool. Of cource my research is about how to use this tool more effectively, but I can stop wondering about the reasons for using this tool.

Why do we communicate? Are we getting wiser or greadier? Do I want to change the world or my self?
