Madness has swept KCRW and they're letting me host Politics of Culture today at 2:30 pm — a half-hour of live radio on the blurred lines between journalism and blogging and between reporting and opinion. My scheduled guests are Joshua Micah Marshall, whose blog Talking Points Memo recently won a Polk Award for reporting on the politicizing of U.S. attorneys; Jay Rosen, NYU professor and blogger and the creator of NewAssignment.Net; and Mark Glaser, blogger and editor of PBS MediaShift. You can listen at FM 89.9 at 2:30, stream it live on the web or catch it later at KCRW.com or on iTunes.

More LAO on the radio: SoCal Sports Observed contributor Phil Wallace hosts "The Zone" on USC's KSCR 1560 AM from 12 to 1 pm today. You can also hear it on KSCR.org. And Mark Lacter's weekly spot on KPCC shifted times today due to the station's pledge drive; listen to it here.
