Ha, that's a great observation; I hadn't thought of it. On one hand, I'm very uncomfortable with any implied comparison to the most well known practitioner of parables. On the other, many others have used the form. Maybe I'll write all my HN posts in parable form - 'those who have ears to hear' will understand; the others I won't have to deal with. I could use it for business emails too.
Coming up with that many parables might be challenging.
It's a really effective technique for getting a point across to most people if they'll give you the time to listen and you're a good storyteller. It's a bit less effective in highly nerdy spaces but still worth doing.
I actually replied to you ask who you were referring to, since I had no idea, but then another comment said who it was so I deleted my reply.
I clearly am never going to be able to use the word "parable" again. I'll say fable from now on, even though fables have animals in them, not humans.
