Is D.J. Wilson a man or a woman? Is D.J. a churlish cynic or a lovable lout? Is D.J. the long-lost twin of St. Louis American editor Alvin Reid? Curious readers of Wilson's weekly "Short Cuts" column in the Riverfront Times get some clues on Mondays at 7 p.m. on Collateral Damage, a KDHX (88.1 FM) program that made its debut July 30. Wilson bills the show as the thinking man's Donnybrook, except that this collection of pontificators features working journalists you don't have to see. What a wag! Wilson's still working on the space-time continuum -- first-show caller Ald. Sharon Tyus (D-20th) tested the limits -- but guests come straight from the local talking-heads A-list, folks such as mayoral aide Jeff Rainford and Prosecuting Attorney Jennifer Joyce. Post-Dispatch columnist Greg Freeman, himself a sort of media Renaissance man, called the show "a bit quirky and unconventional, and lots of fun." Charles Jaco, watch out!
