Like last year, the sidewalks around San Diego's convention center are empty and no one is lined up at the famed Hall H. The streets around San Diego's convention center are empty — no zombies are shambling through the streets and no impromptu campsites have sprung up in the massive line outside Hall H (where all the best panels are), because there are no lines this year. For the second year in a row, San Diego Comic-Con has gone online only. The convention officially kicks off Friday, though some events have gone live already. Panels, the art show, the dealers' hall and the Eisner Awards — generally described as the Oscars of comics — will all be available through what organizers are calling Comic-Con@Home.
