Ann Marie Lipinski may be the most powerful journalist in Chicago. She climbed to the top of the Chicago Tribune masthead in February, becoming the first woman to edit the daily in its 154-year history. In a long career there, she’s already put her mark on the paper, promoting good writing (some say at the cost of solid reporting) and advancing her crew of literate colleagues (dismaying others on the staff). She’s got more plans, including a redesign. Still, can her vision lift the Trib?
