The Internet genius behind the popular Web site committed suicide at his Brooklyn home, police sources and friends said.
Cops found Aaron Swartz, 26, unconscious at 9:30 a.m. Friday in the bedroom of his Sullivan Place apartment building in Crown Heights, law-enforcement sources said.
He had used a belt to hang himself and left no note, the sources added.
Swartz helped create Reddit and drafted an early version of the RSS format, a Web feed that syndicates frequently updated online work, including news, blogs and audio.
