TED Talk hosted by Christopher "moot" Poole, he discusses how there is a growing lack of privacy on the internet, and how his website, 4Chan, allows for people who keep bottled up to be anonymous and speak freely.
Though problems do arise with such a free website that nearly has no guidelines and the people can say and post whatever they want, it also provides a safe place for people who can't speak what's on their minds to others.
What's interesting is the fact that people that into social networking are so comfortable with putting themselves out there, but at the same time don't or can't be their true selves. In today's society, little things a person could say could be heavily criticized and demeaned, making the social network environment seem somewhat hostile and unaccepting, which is why there are fake identities of which the users make up things about themselves to seem more appealing to others.
Luckily, there are others that feel the same way. What's interesting is that there was someone out their who understood enough to make 4Chan so people could be themselves without having others know who they are.
