This can't be good

Air America Radio CEO Mark Walsh said Monday he has left the liberal radio network. The Chicago Tribune, which seems to be covering the Air America experiment more closely than anyone, also reports that Dave Logan, the vice president for operations and programming, has been replaced.

Chairman Evan Cohen characterized the management departures as the normal growing pains of a start-up.

"Businesses have an evolutionary process," he said. "If you're looking for 'Shake-up at Air America Radio,' that's a creation in your own mind."

What I'm looking for is an Air America station in Los Angeles. Their last word on that a week ago was that the local affiliate would be disclosed "shortly." Chaotic first month indeed, as the Tribune notes.
