I recently answered this question: Did Twain mean the coin should be enlarged or not? But after answering it, I began to wonder what it actually has to do with literature. It's about a speech given by a man who happens to be most famous for writing books, but the speech itself wasn't about literature. Should such questions be on-topic?
If the answer is yes, then I fear we may be opening the floodgates to questions about anything that's ever been said by anyone who's ever written literature. Do we really want questions about, say, Winston Churchill's WW2 speeches, just because the man won a Nobel Prize for Literature?
