Thanks for the link.

Keillor's remarks are thoughtful, and perhaps a bit spiteful. I think he 
was jealous of The Man. If you say "Garrison Keillor" in 2110, will 
people know who you mean, or will they say, "Say what?" I think ol' 
Garrison knows that's what they'll say, if they don't just say "Eh?", 
and I think he'd like to feel that someone will write a NYT review of 
his autobiography on that distant day.
