The Chicago Tribune hasn't missed a day since the Great Fire of 1871, but on Monday it almost didn't publish. What is being called a software glitch crashed the production system and prevented 40% of the paper's subscribers from getting the paper. "Those that did got a truncated version with strange page numbering and unusual placement of some features," the Trib reported. Also Monday, in the midst of embarrassing revelations about inflated circulation numbers, the publishers of Newsday and Hoy — the Tribune papers implicated — abruptly retired. In Monday's edition, four Newsday reporters ran a revealing investigation of their own paper. Meanwhile, L.A. Times staffers watch Tribune stock keep dropping, wary about what backlash in Chicago could mean in Los Angeles.
