This is primarily because the main host had a falling out with one of his previous co-hosts for doing a more popular podcast (with Dana Snyder) so he decided to get a new host and resume as if nothing really happened.
The new co-host ain't bad but the only reason I used to listen to the show was because of the previous co-host.
Even ignoring the co-host change, the quality has taken a significant dip. It's a bummer, really.
