On the off-off-off-off hand chance that Bill Maher's people read the liberal blogs, I have a suggestion for his show:
Before the show starts, please take a moment to tell your guest panel to make sure that everyone gets equal time. Tell them that taking turns to speak is a good thing, and to not dominate the conversation - no matter who they are.
Bill, maybe you could have a secret symbol to signal to your guests when they are over-talking. You could tug your ear or something. That would have been helpful two weeks ago with Eddie Griffin and last week with DL Hughley. Hughley was alright, but the editor of Vanity Fair, Graydon Carter, hardly got a word in edgewise...and he was extremely interesting.
