Completely agree with you. However, I think over time I've come to realize that those hacks that seem obscure, weird, and impossible are not perceived that way by the people who discover them. It's just their area of expertise, their natural playground. And so maybe those exploits are as easy to understand by others in that field, as this blog post is to you.

Yes. Things always look way harder from the outside.

Also, the fact that clarity of exposition is interpreted as triviality is why people are sometimes compelled to write things in a way that deliberately obscures the content — one doesn’t want to risk explaining it too well and having the reader think “well, I could’ve come up with that!”.
