I don't know who The Agitator is, but (s)he has Jon Stewart pegged perfectly, including his careful selection of when to be Mr. Kill You with a Smile with his guests, and when to fawn. This is smack on:
"Stewart’s interviewing skills are suffering, too. When he interviews people he disagrees with, he can be brilliant. When he interviews Democrats, he tends to sound like he’s hosting The Chris Farley Show."
