Indeed I found an interesting article from Computer Magazine dated September 2011 about Cyberbullying. This is a research achievement from MIT Media Lab to create a novel social network software that can prevent from bullying.
As you know well, social network has a major impact on the Internet usage today for teenager and adult. It is a place to connect people, make friend or even more. However, some gangs or a group of people may take advantage of it to bully a kid, for example. So that that kid may feel scare, isolated, or s/he bans him/herself from using the Internet.
