The video below is a a face-to-face interview that nicely portraits what Aaron Swartz stood about.
It's hard to add something new to the world tribute about Swartz.
Perhaps you remember that back in 2011 he was charged for his downloading about 4 million academic journal articles via JSTOR, a service that provides students and researchers access to a limited number of articles free of charge.
Or, his role in preventing SOPA. Because of his obvious leadership in activism for internet freedom, many think that his hanging was not exactly accidental. It would be a sad sad world indeed if the rumors were true.
