Hugh Pickens writes "Kevin Kelly has an interesting post about a letter he found amongst correspondence from his days editing the Whole Earth Catalog. The letter is Robert Heinlein's own nerdy solution to a problem common to famous authors: to deal with fan mail. In the days before the internet, Heinlein's solution was to create a list of frequently asked questions, answer them, and remove the questions. Then he, or rather his wife Ginny, checked off the appropriate answer(s) and mailed it back. Some of the entries in Heinlein's answer sheet are quite illuminating and amusing. Our personal favorite: 'You say that you have enjoyed my stories for years. Why did you wait until you disliked one story before writing to me?'"
