What is a "good" blogger

Thanks to Linda Coburn, we have the link to this conversation between Andew Sullivan and Mar Ambinder. Sullivan is a prominent blogger and political commentator. He is consider a pioneer in political weblog journalism, since he was one of the first prominent political journalists in the United State to start his own personal blog. He collaborates to the Atlantic Monthly and is a former editor of The New Republic. Ambinder is an associate editor of the Atlantic and is blogging the 2008 election from the roadshow.
