I've always meant to read something by him. When I was in high school, I did a lot of research on literary censorship, especially in the public school system. His name came up so often, but true to the topic I was researching, his books could not be found in the school library.
So it goes...
(thats the refrain from "Slaughterhouse 5" btw...)

Well... I'm sad. He was by all accounts an obnoxious misanthrope, but he wrote the most fantastically wise and humane literature. Also, often wickedly funny...

"Live by the harmless untruths that make you brave and kind and healthy and happy."
Cats Cradle, 1963

"We are what we pretend to be, so we muust be careful what we pretend to be."
Mother Night, 1961
... and so it goes I guess..

Cat's Cradle was always my fave of his. Ice-9. What a superb conceit.

It is very sad. First Baudrillard, now Vonnegut.

Soon, all of my childhood literary heroes will be gone. It's a sobering thought. At least we still have his works.
I've always considered Vonnegut to be my favorite author. I've given copies of Slaughterhouse Five to friends. My copy is an old paperback bound with this horrible green tape that still keeps it together. He'll definitely be missed. I really regret that I missed the one chance I'd have had to meet him.

A friend of mine posted what I felt was a unique tribute in his blog.
I cried when I read that he was dead, last night. I read all of his stuff over and over when I was growing up. It only got better with the rereading. I never knew him personally, but I miss him being in the world all the same.
