Bennet is "on top of" Website

A quote from Media Bistro:

Bennet says that he has been surprised to find that more than half of his time is spent on The Atlantic's Web site -- keeping on top of online content, navigating the "relationship between a very turbulent Web site of ideas and a monthly magazine of ideas," and planning for the site's future incarnations.

He must smell the big greasy dump Sullivan is taking on his magazine's reputation. Bennet is not ignorant of Sullivan's heinous smears, lies and Jew-baiting. He either can't stop Sullivan, in which case he shouldn't be editor, or he lets Sullivan continue, in which case he is complicit.
