Some consider Sean to be a second-rate shill just out to promote his own books.
Me personally, I have no problem with him shilling his own books. Best of luck to him in that endeavor. He is a second-rate radio host, though. Constantly interrupting his callers and guests grates on me. I hardly listen to him anymore.
I don't listen to him too much either anymore - feel like I have heard all he has to say. Plus - I hate that he calls jerks like Charles Rangel "My Friend."
