Picking a favorite poster is like picking a favorite book or movies. It depends on the mood you're in. Too, who is posting regularly shifts and changes over time, so a list of this sort is impractical. However, I will say that whether I agree or disagree with them I currently enjoy reading DebraD, Bodyguard, and Angry Chicken. I find that regardless of topic their posts are entertaining or thought-provoking and this remains true whether lengthy screeds (this would refer to the men, Deb is more concise as women generally are) or quick jokes. They're all three enjoyable debate opponents, whether I'm engaged myself or reading them debate others.
