The name Aaron Swartz may be unknwon to most of us, but in the internet world it was synonym for free circulation of ideas and a lot more.
He was co-founder of RSS1.0 
CreativeCommons
and Reddit
which internet users enjoy all over the world.
More important, he strongly opposed SOPA (Stop Online Piracy Act).
Unfortunately, this 26-year-old man committed suicide in New York City on January 11, 2013.
