Where's Trilby Lundberg, NPR?

In 2008, the last time gasoline prices were this high, Trilby Lundberg was a near constant guest or source on National Public Radio (NPR)’s Morning Edition and All Things Considered. Ms. Lundberg is a consultant specializing in gasoline price predictions, she’s a peak oil prophet, and she’s still active. But I didn't recall hearing her name mentioned at all this year on NPR. A search of NPR’s archives shows the last time she appeared was July 2008. I wonder what happened in late 2008 to the present that would keep NPR from inviting Ms. Lundberg back to discuss gasoline prices? It was almost as if NPR decided that talking about gasoline prices was no longer interesting after 2008. Hmm.
