Who: Slate columnist Matt Yglesias
What: "Conventions around dead people are ridiculous," Yglesias tweeted upon hearing that the conservative blogger Andrew Breitbart had died. "The world outlook is slightly improved with @AndrewBrietbart dead [sic]."
Why it's dim: Breitbart died suddenly at the age of 43. He leaves a wife and four children. It might take a week or so before Yglesias realizes that he was being a total jerk.
Cure: We know you went to Harvard, Matt, but you still aren't the judge of which people the world would be better off without.
