From Friday, "A Joke..." has 6 references.
From Saturday, "Have They No Shame? No, Actually, They Don't" has 14 references (10 when I looked last night)
From Sunday, "The Insanity of the American Left" has 15 references (6 when I looked last night).
Also from Sunday, "Baathist Surrender In Works?" has 4 references (2 when I looked last night).
From this alone, I think,
- People love a joke about Osama Bin Laden dead and disappointed (or maybe they like puns).
- Attacking "the left" gets lots of responses.
- Good jokes are more popular than (possible) good news from Iraq, neither of which can compete with attacking "the left."
