Attention Air America: It's gotta be entertaining. That's the advice I'd give to the attempt at a "progressive" answer to the conservative bent that seems to dominate talk radio. The network has not yet found a Detroit home, heard in Motown only on XM satellite radio channel 167. Al Franken, Janeane Garofolo, Ed Schultz and Randi Rhodes are trying to prove that there is a market for Left leaning listeners. But if the early air checks are any indication, it may take some time for them to find their groove. All Janeane's Majority Report did for me the other night was itch my button-punching finger.
