Out of nowhere, it seems to have become a fad in podcasting to do really extreme pans. In some cases recently, I've heard interviews where one voice was 100% in the left and one 100% in the right. That's a really bad idea because I for one often have only a single earbud in as I am walking around. When I hit one of those, I hit skip and move on. If I'm really pissed off about it I just delete it.
