“Letter From Cuba: The Religious Revival of a Communist State”By Antal Neville
"When I went to my very first sf convention, which was Worldcon in 1966, I'd already published six or seven novels. A very young man came up to me and said, 'You wrote a book called Babel-17?' I said 'Yes, indeed I did.' He said, 'That stuff, where three people get together and they all do it at once . . . is that possible?' I said, 'Yes.' And he gave an immense sigh of relief and turned around and walked away. At which point I thought, 'I am doing something right.'"
