And at Politico, "Breitbart crashes Netroots Nation":
As Breitbart struck up a conversation with Slate blogger Dave Weigel, Ryan Clayton, who works for US Uncut and blogs on 100ProofPolitics, accosted Breitbart and began screaming questions at him: “Have you kicked your cocaine habit?”Breitbart has a crew with him, but most other hot-button conservatives I've met --- David Horowitz, Michelle Malkin, for example --- travel with bodyguards.
“I have no cocaine habit,” Breitbart told him.
“Have you ever slept with a prostitute?” Clayton asked, almost physically trembling as he worked himself up.
“You prove my point,” Breitbart told him, evidently satisfied that he was again the center of attention in hostile territory.
Another person asked Breitbart if he was credentialed to be there. He admitted that he was not. He tried to walk into the exhibition hall and was turned away by conference organizers.
As he walked back toward the escalator to leave, a middle-aged African-American woman walked toward him and began yelling: “You are racist! … It’s gonna come to light who you really are!”
Chomsky didn't need one at UCLA, of course. The place was filled with communists, hippies, and jihadis.
Added: Blazing Cat Fur links, and there's a thread now at Memeorandum and Wall Street Journal, "Breitbart Sparks a War of Words at Netroots Nation."
