I doubt that's why authors use this technique, though. I think it's part humble-brag ("hey I'm so smart I don't take complexity seriously!") and part an expression of nervousness ("it's scary to write things and publish on the internet, because haters"). A less serious style also allows you to take criticism more easily, perhaps.

That's an explanation, not an excuse! I like dense, solid prose more.

Hmm you're right, on a related note patching holes in my understanding of a topic with "distance" and sarcasm is something I'm personally guilty of. I'm grateful of HN for being much less conductive for that style than, say, Reddit.
