I think that kind of explanation--explaining what you want to explain, with whatever tangents you like, just to get the other person to feel passion about the topic--is great, and can leave you feeling more invigorated than when you started.

But it's a very different kind of explanation than "here are all the building blocks you need to put together in order to understand how wrong the way you're currently doing things is." The second kind is pretty much what all "innocent programming questions" require in response.
