Computer prodigy Aaron Swartz, who helped develop RSS and co-founded Reddit, has been found dead weeks before he was to go on trial on federal charges that he stole millions of scholarly articles in an attempt to make them freely available to the public. Swartz, 26, hanged himself in his Brooklyn apartment, his family in Chicago confirmed in a statement Saturday. He was pronounced dead Friday evening at home in the Crown Heights neighborhood, Ellen Borakove, spokeswoman for New York's chief medical examiner, said. As a young teenager, Swartz helped create RSS, a family of Web feed formats used to gather updates from blogs, news headlines, audio and video for users. He co-founded the social news website Reddit, which was later sold to Conde Nast, as well as the political action group Demand Progress, which campaigns against Internet censorship.
