First Blog- An Introduction and a Question ?

Well, look at this, I'm blogging.
Allow me to introduce myself. I'm working on a documentary that explores the environment created by the technological communications used by the young adult and youth generations of today, i.e. the internet- blogs, youtube, socializing networks such as myspace, email, cell phones, etc.
As a member of the former group, I have noticed the increased use of these communications among my peers and the notice taken by the trend trackers and marketeers of the world.
We live in a time of the most democratic media ever, made possible by the internet, where finally everyone can take part. We are exceedingly more able to be in touch with each other, and through more mediums.

What awareness should we have about these technologies? How are they changing not only the ways that we communicate, but the communications themselves?
And also, what is the grand potential? In a time when young people all over the world have the opportunity to share in multimedia dialogue and exchange experiences and world views, can this new technology be used for something more than narcissism and trivial exchange?
