How, as a writer of riddles, can I rate their difficulty?
I guess, for me alone, knowing the answer even before the riddle existed, it's pretty much impossible, and I should need some external help. Are there some riddling communities or something like that, who could help rate the difficulty? How would I approach this problem?
Edit: to clarify. I mean classic riddles based on metaphors - like the ones found in Tolkien's books. Not 'trick questions', math problems posed as riddles, or other weird riddle-like creatures.
