My opinions...

The greatest fiction writer in English of the 20th century:

Ernest Hemingway. No contest. The champ. And for those of you who haven't read him, or who read The Old Man and the Sea in high school, he was, no, not macho, but rather very sentimental, more along the lines of the feminine sterotype, and no, he didn't use short, simple sentences all the time, but is often very convoluted and complex, just like Gertrude.

Ezra Pound. Sure, he was a fascist. That doesn't mean I support fascism.
